A possible solution is to query for the element/attribute first



   <xsl:if test="rdf:Description/(tiff:XResolution | @tiff:XResolution)">

    <xsl:value-of select ...

   </xsl:if>

   
 Is there another way to do this?

Well XPath 2.0 has an if..then..else expression so instead of using the 
xsl:if construct you could put the check into the select e.g.

  <xsl:value-of

    select="if (rdf:Description/(tiff:XResolution | @tiff:XResolution)) 
then ... else ()"/>



Of course that does the same check but it is a bit shorter.
