How do I check if an element is empty (even if it has other child
elements)?
I am using xmlns:xsl="http://www.w3.org/TR/WD-xsl";...

I can't help you if you are using an old XSLT processor that conforms to
the
old WD spec.  Most people on this list would advise you to upgrade first.

You appear to want to test for text nodes inside descendant elements of
GT1.
An element like <DOB></DOB> will have no contained text node.

If you were using a 1.0 spec-compliant processor, the following would
work:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
   <xsl:template match="/">
      <contains>
         <xsl:if test="not(GT1/descendant::*/text())">
        <empty />
         </xsl:if>
      </contains>
   </xsl:template>
</xsl:stylesheet>

Kind regards,

James Carlyle
