RE: Recursive Split

There is a two-argument version of id() in XPath 2.0. The first argument is
the ID value that you want to find, the second identifies the document that
you want to search, which defaults to "/". If the context node is an atomic
value then you need to supply the second argument.

But if it's really as simple as this:

    <xsl:variable name="item" select="tokenize($item, '\s+')"/>
    <xsl:for-each select="$item">
      <xsl:value-of select="id(.)"/>
    </xsl:for-each>

then just do 

<xsl:value-of select="for $t in tokenize($item, '\s+') return id($t)"/>
