Hallo Henry,

HZ>      Variables that are declared by a template are stored in a stack frame
HZ> (org.apache.xpath.VariableStack) at run-time.  The fix-up process finds

HZ>      I hope that helps.

Yes, thank you! The use indexes seems to be a very popular concept in the XalanJ world.

Greetings,
Daniel
