RE: [xsl] keys and variables

["Michael Kay" <mhk@xxxxxxxxx>]

This is nothing to do with keys.

You're heading towards a meta-stylesheet: a transformation written in XSLT
that converts your abstract (or generic) stylesheet into a concrete
stylesheet. This is a perfectly feasible thing to do but you need to think
very carefully about what you are trying to achieve.
