RE: Infinite Loop when param empty

Thanks for the input on the "Infinite Loop".
Is it good practice to explicitly ask for the top level element in the
select property?  So, the xml source being passed in may look like:

<XML_SOURCE>
  <XML_DATA/>
  <XML_DATA/>
  <XML_DATA/>
</XML_SOURCE>

And the parameter looking like:
<xsl:param name="ENTRY_TEMPLATE" select="XML_SOURCE"/>

Yes, the system is behaving correctly - it is doing exactly what you asked
it to do. And yes, it might be a good idea to ask it to do something
different!
