> . How would I implement keys to clean up and speed up this expression?

the expression is of the form //something[path/to/@attribute=expression]
which is exactly (more or less:-) the meaning of
key('k',expression)
if you first go
<xsl:key name="k" match="something" use="path/to/@attribute"/>

isn't really in that form. I suspect, short of actually throwing the
entire sheet in here for inspection, that I've hit the end of the road
for this one.
