RE: [xsl] Revision Marking in HTML

["Michael Kay" <mike@xxxxxxxxxxxx>]

Without trying to do detailed work on it, it feels to me as if a solution
such as the following might work:

<xsl:template match="text()">
  <xsl:choose>
    <xsl:when
test="name(preceding::processing-instruction()[1])='xm-insertion_mark_start'
">
      <span class="revcontrol">
        <xsl:value-of select="."/>
      </span>
    </xsl:when>
    <xsl:otherwise>
       <xsl:value-of select="."/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
