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.

<plug> 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:

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.
