[QTI] QTI2 quiz with multiple attempts

[Steve Lay]

At the moment, QTITalk doesn't do QTI v2.1 I think, so there isn't 
actually a place that talks about maxattempts other than the 
specification itself (and of course, the XSD with your favourite schema 
viewing tool).

Maxattempts is not an attribute of <assessmentItem> and QTI2 doesn't 
contain an element called just <item>.

If you follow the links under:

http://www.imsglobal.org/question/index.html

You'll see the current QTI2 document set.  The following link takes you 
directly to the definition of the class containing the maxattempts 
attribute.

It can only be applied to items, not to whole tests.  This is an issue 
with the scope of QTI.  It doesn't extend to issues of scheduling, 
retaking tests and so on.  These issues are considered outside the scope 
of the test *content*.  If you look at the place in your system where 
you record other limits on the test, such as when it can be taken, where 
and who can take it, that is probably the best place to encode rules 
about whether people are allowed further attempts or not.
