Can someone answer this question? I'll paste the full stylesheet at the bottom.

I'm getting this error though:

A sequence of more than one item is not allowed as the second argument of concat()
Here's how I've defined the top-level variables:

<xsl:variable name="bibkey" select="//db:biblioref/@linkend" />
<xsl:variable name="bibrecord" select="doc(concat('bib-data/', $bibkey, '.mods'))" />
<xsl:key name="biblio" match="//mods:mods" use="@ID" />

Why am I getting that error then?
