What I need to be able to determine is if an enumerated type is used in
  more than one equipment. 


<xsl:template match="EnumeratedType">
<xsl:value-of select="Name"/>
 <xsl:if  test="../Equipment[Message/Field[EnumeratedType=current()/Name]][2]">
  There are at least 2 of these...
 </xsl:if>
</xsl:template>
