Hi, Daniel.
I just realized that I composed but never sent this response to your
question about variable "fix-up" in Xalan-J.

Variables that are declared by a template are stored in a stack frame
(org.apache.xpath.VariableStack) at run-time. The fix-up process finds
the integer index into the stack frame for each variable reference in an
XPath expression. When an expression is evaluated, the expression
evaluation for a variable reference uses the index to look up the value in
the stack frame, instead of looking up the value by name.
I hope that helps.
Thanks,
Henry
