Hi,

Personally, I'd put the test on the citau element itself:

<xsl:template match="citau">
   <xsl:if test="not(following-sibling::*[1]/self::delim)">
     <xsl:message>citau does not followed by delim</xsl:message>
   </xsl:if>
</xsl:template>

This has the following advantages:

* It expresses the requirement directly (a 'citau' must be followed 
by a 'delim')
     and therefore more legibly
* It is more robust (it doesn't matter where the citau is; it doesn't
     report a false positive if a 'citau' is not found; it doesn't fail
     to report if two are found and one has a 'delim')

As so often, the theoretical and the practical advantages reflect one another.

Cheers,
Wendell
