In Xalan, generate-id() is based on an internal "node ID" number already 
associated with the node, so it's pretty much int-to-string plus a 
concatenate (since the ID has to start with a letter). That's probably a 
bit more expensive than building a nodeset followed by checking its 
length, but not enough that you're likely to notice it unless it's in 
the innermost layer of a tight loop.

If there's a real-world use-case where it does make a real performance 
difference, I'd be interested in knowing about it. Either idiom could 
probably be special-case optimized, but I wouldn't suggest investing 
coding effort in doing so until that's shown to actually make a 
difference -- there are lots of other places to invest tuning effort.
