Thanks to everyone that replied. That will be doable although the  
attribute seems a little unwieldy with several hundred var elements  
listed in some cases. It does make it impossible to do XPath to  
process node lists during transformation presentation. I wanted to  
XPath all var elements that belonged to a specific group/topic.  
Instead I imagine I'll have to recursively parameterize the attribute  
string and chop off a var each visit.
