Query for one or several numbers, possibly with units.
A tolerance parameter should be used to determine how closely the system will require the student’s answer to be in order to count it correct. The tolerance will default to zero if it is not defined. The tolerance parameter should always be defined for a numerical problem unless you are certain only integer answers are generated from your script and you want students to reply with exactly that integer.
A significant figures parameter tells the system how many significant figures there are in the problem, as either a single number, e.g. 3, or a range of acceptable values, expressed as min,max. The system will check to make sure that the student’s answer contains this many significant digits, useful in many scientific calculations.

Incorrect Answers
When switched into exam ("bubble sheet") mode, LON-CAPA usually create wrong answers automatically. To specify wrong answers yourself, you need to provide an array of incorrect values in this attribute. You need to provide at least as many incorrects as 1 less than the number of bubbles on the exam. You can provide more if you want to.

<xs:attribute name="unit" type="xs:string">

Expected units for the answer. For instance, "m/s^2" or "km/(A*hr)".
LON-CAPA will automatically perform some conversions between units of the same dimension when units are provided for a problem. You can provide an answer of "1.45 km" for a distance. If the computer expects the answer in cm, it will convert your answer before comparing against the numerical solution.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="format" type="xs:string">
<xs:annotation>
<xs:documentation>
You can format the number displayed by the computer as the answer. For instance, if the answer is one-third, the computer will display that it computed ".333333333" as the answer. If you'd like to shorten that, you can use the Format field. Format strings like "2E" (without the quotes) will display three significant digits in scientific notation. Format strings like "2f" will display two digits after the decimal point. Format strings like "2s" will round a number to 2 significant digits.

Background plot(s) for answer (function(x):xmin:xmax,function(x):xmin:xmax,x1:y1:sx1:sy1:x2:y2:sx2:sy2,...)
This is a green curve the computer will display once the correct answer has been submitted. It is static, and can be given as a piecewise function.
Since some problems will have multiple correct answers, this necessarily will only be a possible answer. Only the left hand side of the equation is necessary. For example, entering x + 2 will display the line y = x + 2.
The syntax must be syntax recognized by GeoGebra. To test syntax for Geogebra directly, visit http://www.geogebra.org/webstart/geogebra.html .

Within the value argument, the function itself can be evaluated using &fpr_f(), its derivative using &fpr_dfdx(), and its second derivative using &fpr_d2fdx2(). This allows for a comparison of two points on the graph. The value of a previously defined label can be retrieved using the function &fpr_val(), e.g., &fpr_val('positive').

This allows for a margin of error in the y-direction. For instance, if the rule requires that the derivative be equal to 5, the server will accept values close enough to 5 that are within the percent error defined here. Note: Choosing 10% would not mean that the answer is correct as long as it is within the range 4.5-5.5. Instead, the percent corresponds to the total size of the graph. For the function itself, the 'percent error' is multiplied by the ymax-ymin; for the first derivative, it's multiplied by (ymax-ymin)/(xmax-xmin); for the second derivative, it's multiplied by (ymax-ymin)/(xmax-xmin)2; and for the integral, it's multiplied by (ymax-ymin)*(xmax-xmin).

- LONCAPA student response full text of what the student entered in the entry field
- LONCAPA correct answer contents of the answer attribute
- LONCAPA language specified language encoding of the requesting resource
- all items in the form attribute if any of these clash with the above, the above values will overwite the value in the form attribute
The response of the remote server needs to be in XML as follows:
- loncapagrade: takes no attributes, but must surround the response.
- awarddetail: required. The delimited text inside must be one of the detailed results that appears in the data storage documentation. CVS:loncapa/doc/homework/datastorage, look for resource.partid.responseid.awarddetail.
- message: optional message to have shown to the student.

The first part of the hint is the condition, which includes a specification of the foil(s) and foil answer(s) required to trigger the hint. The answers specified in the hint condition are compared with the user's submission, and if the condition is met, the hint action included in the conditional hint block will be executed (for example this could be the display of a block of text). You can set multiple hint conditions for a particular problem. Hint conditions are identified by a name. The corresponding hint action includes this hint condition name in the "on" parameter. When a hint condition evaluates to true, the corresponding hint action is triggered. Besides providing hint actions within <hintpart on="NAME"> </hintpart> tags for each named (NAME) hint condition, a hint can be designated for display if none of the conditional hints evaluate to true. The default hint is not displayed if the conditions were met for any of the conditional hints. The defau!
lt hint action is included between <hintpart on="default"> </hintpart> tags.

Radiobutton Hint Condition
The radiobutton hint tag takes two parameters: answer and name. The name is the name of the hint condition, and the answer is an array. The first element of the array will be 'foil'; the remaining elements are the names of the foils that you require to have been checked by the student for the hint to be displayed. For example, if you create a radiobutton response problem with six foils named: granite, gabbro, gneiss, shale, sandstone and schist, and you want your hint named: igneous to be displayed when either granite or basalt had been checked your radiobutton hint would be as follows:
<radiobuttonhint answer="('foil','granite','gabbro')" name="igneous"></radiobuttonhint>
In order to trigger display of this hint you also need to create a <hintpart> </hintpart> block that will include a textblock that contains the text of the actual hint.

Option Response Hint Condition
There are two types of option response hint conditions: one for standalone foils and one for concept groups. In both cases the option hint tag includes two parameters: answer and name for standalone foils, and concept and name for foils grouped together in a concept group. For the answer parameter, the names and submitted values for each of the foils that are being included in the hint condition are provided in a hash, i.e., in the format: ('Foil1'= > 'True','Foil2'= > 'False'). In the case of a conditional hint for a concept group, the format of the concept parameter is also a hash that links the name of each concept group included in the hint condition to either 'correct' or 'incorrect' - e.g., < optionhint concept="('buoyancy'= > 'correct','density'= > 'correct')" name="fluids" / > If 'correct' is specified for a named concept then when the conditional hint is evaluated answers for each of the foils selected by a student must be correct for the h!
int action to be triggered. If anything other than 'correct' is provided in the concept hash in the optionhint tag then then students answers will be compared with the set answers for the foils in the concept group and as long as at least one answer is incorrect (i.e., the concept group was not correctly answered) then the corresponding hint action will be triggered.

Unless otherwise noted the linestyles require only 2 data sets, X and Y.
- lines: Connect adjacent points with straight line segments.
- points: Display a small marker at each point.
- linespoints: Draw both lines and points.
Draws a small symbol at each point and then connects adjacent points with straight line segments.
- dots: Place a tiny dots on the given points.
- steps: Connect points with horizontal lines.
This style connects consecutive points with two line segments: the first from (x1,y1) to (x2,y1) and the second from (x2,y1) to (x2,y2).
- fsteps: Connect data with horizontal lines.
This style connects consecutive points with two line segments: the first from (x1,y1) to (x1,y2) and the second from (x1,y2) to (x2,y2).
- histeps: Plot as histogram.
Y-values are assumed to be centered at the x-values; the point at x1 is represented as a horizontal line from ((x0+x1)/2,y1) to ((x1+x2)/2,y1). The lines representing the end points are extended so that the step is centered on at x. Adjacent points are connected by a vertical line at their average x, that is, from ((x1+x2)/2,y1) to ((x1+x2)/2,y2).
- errorbars: Same as yerrorbars.
- xerrorbars: Draw horizontal error bars around the points.
Requires 3 or 4 data sets. Either X, Y, Xdelta or X, Y, Xlower, Xupper. Xdelta is a change relative to the given X value. The Xlower and Xupper values are absolute grid coordinates of the upper and lower values to indicated with error bars.
- yerrorbars: Draw vertical error bars around the points.
Requires 3 or 4 data sets. Either X, Y, Ydelta or X, Y, Ylower, Yupper. Ydelta is a change relative to the given Y value. The Ylower and Yupper values are the grid coordinates of the upper and lower values to indicate with error bars.
- xyerrorbars: Draw both vertical and horizontal error bars around the points.
Requires 4 or 6 data sets. Either X, Y, Xdelta, Ydelta or X, Y, Xlower, Xupper, Ylower, Yupper. Xdelta and Ydelta are relative to the given coordinates. Xlower, Xupper, Ylower, and Yupper are the grid coordinates of the upper and lower values to indicate with the error bars.
- boxes: Draw a box from the X-axis to the Y-value given.
Requires either 2 or 3 data sets. Either X, Y or X, Y, Xwidth. In the first case the boxes will be drawn next to eachother. In the latter case Xwidth indicates the horizontal width of the box for the given coordinate.
- vector: Draws a vector field based on the given data.
Requires 4 data sets, X, Y, Xdelta, and Ydelta. The ‘vector‘ style draws a vector from (X,Y) to (X+Xdelta,Y+Ydelta). It also draws a small arrowhead at the end of the vector. May not be fully supported by gnuplot.

The <tic> tag allows users to specify exact Tic positions and labels for each axis.
In this version we only support level 0 tics (major tic).
Each tic has associated with it a position and a label $current_tics is a reference to the current tick description hash.
We add elements to an array in that has: ticspecs whose elements are 'pos' - the tick position and 'label' - the tic label.

Randomly Parsed Block
The enclosed tags are parsed in a stable random order. The optional attribute show=“N†restricts the number of tags inside that are actually parsed to no more than N. N can equal the total tags inside. The randomlist tag can be used to randomize problem parts by wrapping the <part> tags with a randomlist tag. Note that when randomlist wraps <part> tags, that all students will work all parts only if show=“N†where N is the total number of parts wrapped. When N is less than the total number of parts wrapped, there will be gaps in the assessment chart, and also in the table of submissions for each student, corresponding to those parts which are never available to that particular student.

<xs:annotation>
<xs:documentation>
This attribute defines a unique identifier (ID) which must be unique in the whole document. Its purpose is to identify the element when linking (using a fragment identifier), scripting, or styling (with CSS).
Usage note:
- This attribute's value is an opaque string: this means that web author must not use it to convey any information. Particular meaning, for example semantic meaning, must not be derived from the string.
- This attribute's value must not contain white spaces. Browsers treat non-conforming IDs that contains white spaces as if the white space is part of the ID. In contrast to the class attribute, which allows space-separated values, elements can only have one single ID defined through the id attribute. Note that an element may have several IDs, but the others should be set by another means, such as via a script interfacing with the DOM interface of the element.
- Using characters except ASCII letters and digits, '_', '-' and '.' may cause compatibility problems, as they weren't allowed in HTML 4. Though this restriction has been lifted in HTML 5, an ID should start with a letter for compatibility.

This attribute is a space-separated list of the classes of the element. Classes allows CSS and Javascript to select and access specific elements via the class selectors or functions like the DOM method document.getElementsByClassName.
Usage note: Though the specification doesn't put requirements on the name of classes, web developers are encouraged to use names that describe the semantic purpose of the element, rather to the presentation of the element (e.g., attribute to describe an attribute rather than italics, although an element of this class may be presented by italics). Semantic names remain logical even if the presentation of the page changes.
</xs:documentation>

</xs:attribute>
<xs:attribute name="style" type="xs:string">
<xs:annotation>
<xs:documentation>
This attribute contains CSS styling declarations to be applied to the element. Note that it is recommended for styles to be defined in a separate file or files. This attribute and the <style> element have mainly the purpose of allowing for quick styling, for example for testing purposes.
Usage note: This attribute must not be used to convey semantic information. Even if all styling is removed, a page should remain semantically correct. Typically it shouldn't be used to hide irrelevant information; this should be done using the hidden attribute.

This attribute defines the character encoding of the linked resource. The value is a space- and/or comma-delimited list of character sets as defined in RFC 2045. The default value is ISO-8859-1.
Usage note: This attribute is obsolete in HTML5 and must not be used by authors. To achieve its effect, use the Content-Type: HTTP header on the linked resource.

This attribute indicates the language of the linked resource. It is purely advisory. Allowed values are determined by BCP47 for HTML5 and by RFC1766 for HTML 4. Use this attribute only if the href attribute is present.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="type" type="xs:string">
<xs:annotation>
<xs:documentation>
This attribute is used to define the type of the content linked to. The value of the attribute should be a MIME type such as text/html, text/css, and so on. The common use of this attribute is to define the type of style sheet linked and the most common current value is text/css, which indicates a Cascading Style Sheet format.

<xs:attribute name="rel" type="xs:NMTOKENS">
<xs:annotation>
<xs:documentation>
This attribute names a relationship of the linked document to the current document. The attribute must be a space-separated list of the link types values. The most common use of this attribute is to specify a link to an external style sheet: the rel attribute is set to stylesheet, and the href attribute is set to the URL of an external style sheet to format the page. WebTV also supports the use of the value next for rel to preload the next page in a document series.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="rev" type="xs:NMTOKENS">
<xs:annotation>
<xs:documentation>
The value of this attribute shows the relationship of the current document to the linked document, as defined by the href attribute. The attribute thus defines the reverse relationship compared to the value of the rel attribute. Link types values for the attribute are similar to the possible values for rel.
Usage note: This attribute is obsolete in HTML5. Do not use it. To achieve its effect, use the rel attribute with the opposite link types values, e.g. made should be replaced by author. Also this attribute doesn't mean revision and must not be used with a version number, which is unfortunately the case on numerous sites.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="media" type="MediaDesc">
<xs:annotation>
<xs:documentation>
This attribute specifies the media which the linked resource applies to. Its value must be a media query. This attribute is mainly useful when linking to external stylesheets by allowing the user agent to pick the best adapted one for the device it runs on.
Usage note:
- In HTML 4, this can only be a simple white-space-separated list of media description literals, i.e., media types and groups, where defined and allowed as values for this attribute, such as print, screen, aural, braille. HTML5 extended this to any kind of media queries, which are a superset of the allowed values of HTML 4.
- Browsers not supporting the CSS3 Media Queries won't necessarily recognize the adequate link; do not forget to set fallback links, the restricted set of media queries defined in HTML 4.

The defer attribute shouldn't be used on scripts that don't have the src attribute. Since Gecko 1.9.2, the defer attribute is ignored on scripts that don't have the src attribute. However, in Gecko 1.9.1 even inline scripts are deferred if the defer attribute is set.

Javascript event handler content attribute for the "click" event.
Warning: event handler content attributes should be avoided. They make the markup bigger and less readable. Concerns of content/structure and behavior are not well-separated, making a bug harder to find. Furthermore, usage of event attributes almost always causes scripts to expose global functions on the Window object, polluting the global namespace.
The EventTarget.addEventListener() function should be used instead to add a listener for the event.

parpic: The picins package \parpic command will be used to place the image. This will wrap the remainder of the paragraph containing the picture around the image.
If, however, there is insufficient text to fill the space to the left or right of the image, the next paragraph may be wrapped on top of the image. In addition, \parpic does not always honor the end of the page, causing the image to extend below the page footer.

<xs:attribute name="accept-charset" type="xs:string">
<xs:annotation>
<xs:documentation>
A space- or comma-delimited list of character encodings that the server accepts. The browser uses them in the order in which they are listed. The default value, the reserved string "UNKNOWN", indicates the same encoding as that of the document containing the form element.
In previous versions of HTML, the different character encodings could be delimited by spaces or commas. In HTML5, only spaces are allowed as delimiters.

<xs:documentation>
Javascript event handler content attribute for the "click" event.
Warning: event handler content attributes should be avoided. They make the markup bigger and less readable. Concerns of content/structure and behavior are not well-separated, making a bug harder to find. Furthermore, usage of event attributes almost always causes scripts to expose global functions on the Window object, polluting the global namespace.
The EventTarget.addEventListener() function should be used instead to add a listener for the event.

<xs:documentation>
See http://www.w3.org/XML/1998/namespace.html and
http://www.w3.org/TR/REC-xml for information about this namespace.
This schema document describes the XML namespace, in a form
suitable for import by other schema documents.
Note that local names in this namespace are intended to be defined
only by the World Wide Web Consortium or its subgroups. The
following names are currently defined in this namespace and should
not be used with conflicting semantics by any Working Group,
specification, or document instance:
base (as an attribute name): denotes an attribute whose value
provides a URI to be used as the base for interpreting any
relative URIs in the scope of the element on which it
appears; its value is inherited. This name is reserved
by virtue of its definition in the XML Base specification.
id (as an attribute name): denotes an attribute whose value
should be interpreted as if declared to be of type ID.
The xml:id specification is not yet a W3C Recommendation,
but this attribute is included here to facilitate experimentation
with the mechanisms it proposes. Note that it is _not_ included
in the specialAttrs attribute group.
lang (as an attribute name): denotes an attribute whose value
is a language code for the natural language of the content of
any element; its value is inherited. This name is reserved
by virtue of its definition in the XML specification.
space (as an attribute name): denotes an attribute whose
value is a keyword indicating what whitespace processing
discipline is intended for the content of the element; its
value is inherited. This name is reserved by virtue of its
definition in the XML specification.
Father (in any context at all): denotes Jon Bosak, the chair of
the original XML Working Group. This name is reserved by
the following decision of the W3C XML Plenary and
XML Coordination groups:
In appreciation for his vision, leadership and dedication
the W3C XML Plenary on this 10th day of February, 2000
reserves for Jon Bosak in perpetuity the XML name

<xs:annotation>
<xs:documentation>This schema defines attributes and an attribute group
suitable for use by
schemas wishing to allow xml:base, xml:lang or xml:space attributes
on elements they define.
To enable this, such a schema must import this schema
for the XML namespace, e.g. as follows:
<schema . . .>
. . .
<import namespace="http://www.w3.org/XML/1998/namespace"
schemaLocation="http://www.w3.org/2001/03/xml.xsd"/>
Subsequently, qualified reference to any of the attributes
or the group defined below will have the desired effect, e.g.
<type . . .>
. . .
<attributeGroup ref="xml:specialAttrs"/>
will define a type which will schema-validate an instance
element with any of those attributes</xs:documentation>
</xs:annotation>
<xs:annotation>
<xs:documentation>In keeping with the XML Schema WG's standard versioning
policy, this schema document will persist at
http://www.w3.org/2004/10/xml.xsd.
At the date of issue it can also be found at
http://www.w3.org/2001/xml.xsd.
The schema document at that URI may however change in the future,
in order to remain compatible with the latest version of XML Schema
itself, or with the XML namespace itself. In other words, if the XML
Schema or XML namespaces change, the version of this document at
http://www.w3.org/2001/xml.xsd will change
accordingly; the version at
http://www.w3.org/2004/10/xml.xsd will not change.
