Re: Itemset alternative (not working)

nks.  I had considered preprocessing, and figured it would
be neccessary for at least the instance document (since the node
metadata *is * in seperate documents).  However, I was hoping I wouldn't
have to preprocess the XForms document itself and would be able to pull the 
dynamic parts I need from the instance document alone.  Even so, I'm not
sure why the solution I went with is causing the select/select1 form inputs
to be rendered uncoupled from the instance values on the nodes they are
bound to.  Now I think about it, I believe the problem is that 
*two* evaluation passes are probably needed by the XForms processor to
1) roll out the xf:repeat nodes and their containing
xf:item nodes 2) setting the appropriate 'selected' attributes.  So, it looks
like preprocessing the XForms document is inevitable until itemset is
implemented.
