The key() function selects nodes within the current document - that is, the document containing the context node. If there's no context node then it doesn't know which document to search. Write $from/key('teams', $team-refs). Michael Kay

Thanks a bunch. Sounds logical now that you mention it, and explains why <xsl:key> doesn't require a full xpath in its match attribute. I was mistakenly drawing a parallel between a global var and a key (also defined at the top-level). BTW, I ran again into the 'Unknown value representation' bug. May I ask if you're considering a 8.5 release soon? Thanks, --DD PS: Did I miss the $from/key() in a function example in your book? Or is it just too much a corner case to document? I fully understand one can't put everything in a book. No complaints, just wondering ;-) PPS: I worked around the issue by using a named template, but I'll switch to a function to make it easily recursive.

I've blocked out a week in my diary during July and hope this will be sufficient to get 8.5 out of the door. I can't immediately spot this example in the book. You can also specify the document to be searched by using the 3rd argument of key(), which is described in the book - note however that the meaning of this argument has changed slightly since the book was published - if you supply an element, then the function will only search the subtree rooted at that element, not the whole document containing that element.
