The XSLT 2.0 solution that comes to mind is:

<xsl:for-each-group group-starting-with="IDM|LV2|LV3">
  <xsl:choose>
  <xsl:when test="self::IDM">
    <phrase>
      <xsl:copy-of select="current-group()"/>
    </phrase>
  </xsl:when>
  <xsl:otherwise>
    <xsl:copy-of select="current-group()"/>
  </xsl:otherwise>
  </xsl:choose>
</xsl:for-each-group>
