RE: IE's conditional comments in xslt

Would you like to describe the problem you are trying to solve, and the
constraints on the solution, that prevent you using XML markup to achieve
this?

Note that XSLT 2.0 has compile-time conditionals achieved through a use-when
attribute. Why doesn't this work for you?
