HTML Comments in XSLT code

<xsl:template ...>
   ...
   <!-- XSLT comment -->
   ...
   <xsl:comment>HTML comment</xsl:comment>
   ...
</xsl:template>

When comments are coded in an XSL template, they are treated as XSLT comments, not HTML comments. The <xsl:comment> instruction can be used in XSLT code to include an HTML comment in a template.
