This is an interesting idea. If there is a known set of equivalent
expresions: Exp1 <---> Exp2 <---> ... ExpN,

then an XSLT processor can choose to implement any expression in the
chain with the one that will be most efficient.

Therefore, it would be very useful to establish and publish a good rich
set of such equivalence-expression-chains.
