[LON-CAPA-admin] xml codes for not to clone the open, due .. dates

[H.K. Ng]

Hi,

What is the xml codes so that the open, due .. dates are not cloned? 
I have a sign up form for instructors and I like to include that 
option. The course request form within loncapa has the following:

<input type="radio" name="datemode" value="delete" />

Does this translate into

<datemode>delete</datemode>?

And should this be placed within <clonecrs> or as a separate tag?

Thanks,
-hk
