Wow, a use case for tunnel parameters. Even if it does not help the
performance (which would not be a problem), it is a cool ,concept and
a good reason to learn about it.
Thanks for the hint,

That's about it really. As an alternative to going back up each time
ancestor::doc you could pass it down as you go along
<xsl:template match="@idref | @id">
<xsl:param name="lang" tunnel="yes"/>
<xsl:attribute name="{name()}"
select="concat($lang, '_', .)"/>
</xsl:template>
and use
xsl:with-param to set this in the template for doc.
However I have no idea on the relative costs of doing ancestor:: or
passing down a tunnel param. Presumably depends on whether you use
an idiom that causes Michael's optimiser to do something clever or
whether the code actually implements the document traversal..
