Common actions can be separted as a "named template".

The syntax is very similar:

<xsl:template name="internal-style">
<style type="text/css">
...
</style>
</xsl:template>

The context node remains the same when it is used:

<xsl:template name="make-attribute">
<xsl:attribute name="altid/@type">
<xsl:apply-templates/>
</xsl:attribute>
</xsl:template>
