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

["Michael Kay" <mike@xxxxxxxxxxxx>]

Sounds like it might be a good idea to do an initial pass that wraps the N
element and its preceding comments in a wrapper element. That's a positional
grouping problem:

<xsl:for-each-group select="child::node()" group-ending-with="N">
  <wrapper>
    <xsl:copy-of select="current-group()"/>
  </wrapper>
</xsl:for-each-group>
