Unless I misunderstand, you just do

<xsl:apply-templates select="id($target)"/>

since the id() function goes straight to the right element, with no
need for any more qualification. That assumes that the ID attribute is 
declared as of type ID in the DTD. If I remember something I read at
Microsoft, their XSL would mean it had to be called "xml:id", because
they don't read the DTD? something like that.

I was delighted to find that id() function. It meant that from
 <code id="GB">Great Britain</code>
 <nat idref="GB"/>

I could get the <nat> to generate "Great Britain" with just
   <xsl:apply-templates select="id(@idref)"/>

Moving all my code lookup tables into the main XML file made by feel
better for, well, minutes.
