I agree, a global variable is about as good as a single-key index (not single-valued!). Though, my 
impression on some XSLT 1 implementations was that the keying mechanism is more optimized to 
traverse the document than the evaluation of //. And accessing a key instead of a variable might 
make a difference as well.

But I agree: there is only one way to find out: measuring it. :-)
