RE: using boolean to compare id numbers

I believe this would require that you sort on @uid. And I also believe
preceeding-sibling selects all preceeding siblings.

I would try something like this ...

<xsl:template match="/">
	<xsl:apply-templates select="//user" mode="check-dups">
		<xsl:sort select="@uid"/>
	</xsl:apply-templates>
</xsl:template>

<xsl:template match="user" mode="check-dups">
  <xsl:if test="preceding-sibling::user/@uid=@uid">
   <xsl:message>oops</xsl:message>
  </xsl:if>
...

Will that test that no two users not just the
preceding user have the same uid numbers?
