Correct.

<problem>
<part id="26">
  <numericalresponse id="11"><textline /></numercialresponse>
  <numericalresponse id="12"><textline /></numercialresponse>
</part>
</problem>

This is 1 problem. The student only gets credit if they supply the
correct answer to both numericalresponses at the same time.

This could be useful in a problem where you are looking for a vector
response, or some other set of related values.

Either way this is a _single_ problem and thus will have a single
entry in the Chart, Spreadsheet, Grades, Navigation screen,
Statistics, etc.

When viewing the students results on the PGRD screeen you will see a
single credit column and a single tries column, but multiple
'submission' and 'awarddetail' columns.


On the other hand.
<problem>
<part id="26">
  <numericalresponse id="11"><textline /></numercialresponse>
</part>
<part id="27">
  <numericalresponse id="12"><textline /></numercialresponse>
</part>
</problem>

This acts as if there are two seperate problems in one.
You can get either the first or second <part> correct, you get
seperate credit for each part, etc.
