If this works, then you're probably using MSXML3, because it relies on the
implicit conversion of a result tree fragment to a node-set. XSLT 1.0
specifically states that the "/" path operator can't be used with a
result-tree-fragment argument.

Correct, variables can't be used in template rules. This is to prevent
recursion: a global variable declaration might invoke the template, so which
comes first?

The match pattern must be fixed "at compile time", it can't depend in any
way on the source document. It might be possible to achieve what you want
using the name() function, but that doesn't help much because you'd probably
want to compare the name with a variable.
