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).
