That would make for *three* user level templates
to generate head content (system.head.content is the
other one). How about if we just move the
call to the user.head.content template to the
end of the <head> element? Looking at the
usage in docbook.xsl, I think that was the original
intent anyway:
<head>
<xsl:call-template name="system.head.content">
<xsl:with-param name="node" select="$doc"/>
</xsl:call-template>
<xsl:call-template name="head.content">
<xsl:with-param name="node" select="$doc"/>
</xsl:call-template>
<xsl:call-template name="user.head.content">
<xsl:with-param name="node" select="$doc"/>
</xsl:call-template>
</head>
If we do this for the chunking templates, then
you would get the last word using the existing
user.head.content template.
