Template has no @name or @match

A template with neither name nor match can be reached by nothing: no xsl:apply-templates selects it, since it matches no node, and no xsl:call-template names it. Its body is dead code, and a processor refuses the module as a static error (XTSE0500) rather than skipping the template, so one unreachable rule stops the whole stylesheet from running. Give it the match pattern it should be selected by, or the name it should be called by.

Incorrect:

<xsl:template>
  <!--body-->
</xsl:template>

Correct:

<xsl:template match="o/o">
  <!--body-->
</xsl:template>

or:

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

or:

<xsl:template name="oo" match="o/o">
  <!--body-->
</xsl:template>
