re-use of DATA-GROUP seems odd, unspecified

From the XML Schema for P3P,
  http://www.w3.org/TR/2001/WD-P3P-20010928/#Appendix_schema
This seems allowed:

	<POLICY>
                 <ENTITY>
                  <DATA-GROUP>
                   <DATA ref="#business.name">
                     <CATEGORIES><demographic/></CATEGORIES>
                   </DATA>
	          </DATA-GROUP>
	        </ENTITY>
		...
	</POLICY>

What would that mean? Why allow <CATEGORIES> in
<ENTITY>? i.e. why re-use the DATA-GROUP syntax?
It doesn't seem to buy anything.

fyi... I'm writing something that converts P3P policy
files to RDF,
  http://www.w3.org/2000/10/swap/p3p/grokPolicy.xsl

trying to see if I can do an APPEL-work-alike
using some Semantic Web Advanced Development stuff...
