<xsl:template name="siteLinks">
<xsl:param name="theLinkGroup"></xsl:param>
<h2><xsl:value-of select="$theLinkGroup" /></h2>
<!----- does
work
<ul class="xsmall">
<xsl:for-each select="//$theLinkGroup/link">
<!-----
won't work
<li><a>
<xsl:attribute name="href"><xsl:value-of
select="url"/></xsl:attribute>
<xsl:value-of select="@title"/>
</a></li>
</xsl:for-each>
</ul>
</xsl:template>
Nearly there, you want:
<xsl:for-each select="//link[parent::*[local-name() = $theLinkGroup]]">
Which roughly translates to 'select all <link> elements which have a
parent element called whatever the $theLinkGroup is, in any namespace'.
