RE: Capturing/testing results of a boolean expression.

Well, the straight-forward answer is to define
the variable as a direct child of <xsl:stylesheet> 
and use the select attribute to evaluate the expression. 
Something like this: 

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

<xsl:variable name="globalVar" select=" (your expression here) "/>

It's really rather hard to tell what problem you are experiencing as 
you don't offer any examples (I know, you want the general solution, 
not a specfic one :)
