  XSLT provides current() too.  But I tend to use variables as you did,
I find that clearer.  In this particular case, maybe an xsl:key would
be better, depending on the complexity of your real input.

I have not used keys before.  Just read about them and here is what I
have so far:

The only thing I don't understand is if the key can handle multiple
conditions, that being both the method ID and the method version.

In case you are wondering the parser that is in use is Microsoft .Net
2.0's XslCompiledTransform which is only XSLT 1.0.
