Re:  "not a node item" inside distinct-values
Others have pointed to teh immediate cause of teh error message, but if
you find yourself doing this: 

> <xsl:for-each select="distinct-values(//item/@racknum)">
>         <xsl:variable name="rack-num" select="."/>
>         <xsl:variable name="pocket-num" select="//item[./@racknum =
> $rack-num and position() = last()]"/>

9 times out of 10 its easier (and probably more efficient) to do


<xsl:for-each-group select="//item" group-by="@racknum">

(also probably //item should just be item)
