Ah, nice one. Googling the documentation of xsl:number would never have
suggested this solution to me. So, to understand correctly, <xsl:number/>
reports the original position in the source elements, while position()
reports the position in the *selected* sub-set of nodes/elements?
Yes, that is it ... though <xsl:number/> works on the entire source
tree not just elements.

If you want more details on <xsl:number/> (it is a very powerful
construct) that happens to be the subject of the YouTube excerpted
sample lesson of our five-day hands-on class recorded as a 24-hour
interactive hyperlinked XSLT/XPath 1.0/2.0 training DVD:
http://www.youtube.com/watch?v=PrNjJCh7Ppg
Of course the YouTube bit isn't hyperlinked ... so to see how that
works there is a download of a "test lesson" that demonstrates the
hyperlinking to each slide:

The DVD runs on Linux (with Totem), Macintosh and Windows platforms,
but I ask prospective buyers to try the above test video first to
ensure the format will run on their platform.
An overview of the entire class is also posted as a YouTube excerpt:

I've been very excited with the feedback from our video customers.

I hope this helps.
