//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.
