Answer 1

You could change:
<xsl:value-of select="." disable-output-escaping="yes"/>
to:
<xsl:value-of select="replace(., '&', '&amp;')" disable-output-escaping="yes"/>
But this is just slapping another hack on top of the other two. The real problem here is that the content of the comment is not XML.
