RE: referring to variables using variables?

XSLT is not a macro language. The content of a variable is a value
(either a boolean, a string, a number, or a node-set). It is not part of
the text of an XPath expression. I think this is where your confusion
comes from.

For example, if $x contains the string 'xyz', then $x/pqr does not mean
xyz/pqr, it means 'xyz'/pqr, which is an error: the operands of the "/"
operator must be node-sets, not strings.
