RE: [xsl] xsl:variable doesn't work here

["Michael Kay" <michael dot h dot kay at ntlworld dot com>]

In standard XSLT/XPath there is no way to store an expression inside a
variable. Or rather, you can store it as a string, but there is no way of
evaluating the expression.

Some processors (saxon, xalan, ...) have an evaluate() extension that allows
this: use xx:evaluate($condition).
