[xsl] Keeping comments with relevant node when shorting nodes

Subject: [xsl] Keeping comments with relevant node when shorting nodes

I have several XML files like the following:

<!-- CNs-->
<Ns>
    <!--CN1-->
    <N name="N1">
        <Ms>
            <!--C1N3-->
            <M name="1N3"/>
            <!--C1N1-->
            <M name="1N1"/>
            <!--C1N2-->
            <M name="1N2"/>
        </Ms>
    </N>
    <!--CN2-->
     <N name="N2">
         <Ms>
             <!--C2N2-->
             <M name="2N2"/>
             <!--C2N3-->
             <M name="2N3"/>
             <!--C2N1-->
             <M name="2N1"/>
         </Ms>
     </N>
</Ns>


I'd like to sort them while keeping comments with the nodes they refer
to (e.g., keep <!--CN2--> with <M name="2N2"/>).

I've tried the following xslt:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
	<xsl:output indent="yes" method="xml"/>

<xsl:template match="node() | @*">
  <xsl:copy>
    <xsl:apply-templates select="@* | node()"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="Ns">
    <xsl:copy>
        <xsl:apply-templates select="comment()| N" >
          <xsl:sort select="@name"/>
        </xsl:apply-templates>
    </xsl:copy>
</xsl:template>
</xsl:stylesheet>

It sorts fine but puts the comments  for all the N nodes together at
the top of the Ns element. I've played around with trying to group the
comments and N nodes using preceding-sibling but have not been
succesful.

Any ideas?

Thanks
