It's a little bit trickier than that, because the XPath expression
identified elements to be modified. Evaluating a dynamic XPath expression to
give a set of nodes is one thing; writing a stylesheet that modifies the
nodes in the result of that expression is another.

Also there are multiple expressions, and doing one pass (i.e. a document
copy) for each expression sounds expensive.

If the expressions are constrained to be XSLT patterns, then it would
probably be easier to generate a stylesheet dynamically in this situation.
