Or count(ancestor::*) + count(preceding::*) + 1 to avoid the cost of
unnecessarily sorting into document order, merging the lists, and
eliminating the non-existent duplicates. (That's one reason I
suggested xsl:number. Another, more important, is that in Saxon,
xsl:number is optimized so that when you make repeated calls with
the same attributes to number successive nodes, Saxon doesn't count
all the nodes from the beginning of the document each time, it only
counts back to the most recently numbered node).
This little bit of information about Saxon is very useful!
Cheers,
Wendell
