You have defined $record as a result tree fragment, so XSLT 1.0 does not
allow you to use it in a path expression. You need the xx:node-set()
extension.

But there's a simpler solution: create it as a node-set in the first
place, by writing:

<xsl:variable name="record"
       select="document(fullKey)/xmldata"/>

I see a great deal of this unnecessary creation of result tree
fragments. Whenever you see

<xsl:variable name="x"><xsl:value-of select="Y"/></xsl:variable>

it should almost always be rewritten as

<xsl:variable name="x" select="Y"/>
