Laura,

I agree with you. Of course at the moment virtually all of the detail of the 
XForms Model per se has still to be defined.

But given some of the examples earlier in the WD ... the credit card one 
comes to mind ... it seems likely that if credit is the preferred method of 
payment then the cardnumber and cardexpiry become "relevant". I assume (or 
suggest) that there should be some way to combine the notion of being 
"relevant" and "required" as per 5.2.4 so that Waleed's desire is met.

Since both the "required" and "relevant" model item properties are stated to 
be computed expressions it looks pretty promising to me.
