[QTI] results reporting

[Steve Lay]

Marina,

This looks much better than your first suggestion, yes.  There is only 
one thing to add.  The baseType attribute of responseVariable is 
optional only because it makes no sense for record types (which have 
specialist uses that you won't normally encounter unless you are making 
extensions to QTI).  So you must include this attribute too just in case 
the person reading the result report doesn't have access to the original 
item and can't figure out whether the value "70" (to take your first 
example) is a number or a string.
