I probably don't want //item.  What I want is all elements named item which
are descendants of the current element - but I am not sure what the syntax
would be (still looking).  I don't know xsl:key or how it could help me - do
you know of a good example/URL?

I have a question about position().  If this xsl:for-each contained an
xsl:sort, the position() values in the select of the for-each would not be the
sorted positions, right?  

<xsl:for-each select="whatever[position() &lt; last()-$remaining]">
<xsl:sort select="somethign">
<!-- would the node position() values here be the same as those in the
for-each? -->

Hopefully I am making some sense and not just confusing myself.
