RE: dyn:evaluate question

We used to get a lot of variations on attempts to do dynamic inclusion, but
this is one of the most imaginative.

xsl:include is a compile time construct, it's effect happens right at the
start of processing, to assemble a stylesheet for compilation. There's no
way a variable can be evaluated before the stylesheet has been compiled, so
trying to refer to a variable here simply isn't going to work.
dyn:evaluate() does things at run-time that would normally be done at
compile-time, it isn't going to enable you to do at compile time something
(evaluating a variable) that can only possibly be done at run-time.

You don't need a workaround, you need a different design: but you haven't
said what the problem is, so I can't give you one.
