RE: [xsl] Linking Variable to the Path

["Michael Kay" <mike@xxxxxxxxxxxx>]

The basic answer is that standard XSLT does not allow you to construct an
XPath expression dynamically from a string. It's a common requirement and
several processors provide extensions (saxon:evaluate, dyn:evaluate) that
handle it - but some do not.
