RE: Chunking xml into single-topic docs

If your logic is as simple as

<xsl:for-each select="chapter">
  <xsl:result-document href="chap{position()}">
    <xsl:apply-templates/>
  </xsl:result-document>
</xsl:for-each>

then I would definitely use position() - it's easy to express and easy for
the processor to calculate.

Using things like <xsl:number/> or count(preceding-sibling::*) is sometimes
necessary but it has a serious risk of being O(n^2) in performance
(depending of course on the optimizer).
