//biblioref selects all the biblioref elements in the document. There is
more than one. Each one has an @linkend attribute. So $bibkey evaluates to a
sequence of (more than one) attribute node. Which means you can't use it as
an argument of concat(). - An example of the stricter type rules in 2.0
catching an error that in 1.0 would have led to garbage output.
I can't correct it for you because it's not clear to me what you meant to
write.

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

I'm getting this error though:

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?
