I think I would solve this either with an extension function,
getSequenceNumber(), which returns a stream of sequence numbers, or with a
two-pass transformation, in which the sequence numbers are added in the
second phase using <xsl:number/> or count(preceding::*). Or perhaps even
with a post-processing SAX filter which adds the id's. None of these is a
particularly "pure" XSLT solution, but when it comes down to doing real
work, I'm a pragmatist.
