Unused named template

A named template that nothing runs is dead code: it costs the reader time and drifts out of date unnoticed. Remove it, or call it.

The check reads every stylesheet linted together, so lint the whole project at once to let it see every caller. A template that only calls itself, or a loop of templates calling only each other, is reported too. The processor enters xsl:initial-template directly, so any template whose name ends in :initial-template is left alone, one of your own in another namespace included.

Incorrect:

<xsl:template name="footer">
  <footer>Copyright 2026</footer>
</xsl:template>
<!-- xsl:call-template name="footer" never appears in this stylesheet -->

Correct:

<xsl:template name="footer">
  <footer>Copyright 2026</footer>
</xsl:template>

<xsl:template match="/">
  <xsl:call-template name="footer"/>
</xsl:template>
