An xsl:template that has no match attribute must have no mode attribute
and no priority attribute. In a named template they have no meaning, since
it is called by name rather than selected among several templates.
Incorrect:
<xsl:template name="oo" priority="2" mode="qq">
<!--body-->
</xsl:template>
or:
<xsl:template name="oo" mode="qq">
<!--body-->
</xsl:template>

<xsl:template name="oo" priority="2">
<!--body-->
</xsl:template>

<xsl:template name="oo" match="oo" mode="qq">
