checking for empty elements?

Hi all,

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";...

XML:

<GT1>
    <Name></Name>
    <DOB></DOB>
</GT>

XSL:

<xsl:if test="GT is empty">
Element GT1 is empty!
</xsl:if>

Thanks a lot,
Gabi.
