It seems this exception is already known as a possible bug: 
http://marc.info/?l=xalan-dev&m=117629991417675&w=2

Are you using the latest Xalan version ?

There are already workarounds in XSLTForms like the one you found for 
other XSLT engines problems. So, I will change this in XSLTForms as you 
suggest. I will contact you again when it will be committed.

Instead of global variables, I prefer having local variables defined and 
used in the corresponding source component (if you have a look at the 
SVN repository, you will see that the xsltforms.xsl file is generated 
from many source components!).
