A couple of comments about the example on your Web page:

   <ELEMENT TAG="FIGURE">
   <CONTENTMODEL>IMAGE,CAPTION?</CONTENTMODEL>
   <ATTRIBUTE NAME="DESCRIPTION">
   <ATTCONTENT>CDATA</ATTCONTENT>
   <ATTREQUIRED>#IMPLIED</ATTREQUIRED>
   </ATTRIBUTE>
   </ELEMENT>

Content model should contain sub-elements, such as <ELEMENTUSE>, not text.  You 
don't want to force applications to parse text.  On the other hand, attribute 
descriptions are probably better stored in attributes:

   <ATTRIBUTE NAME = "DESCRIPTION" CONTENT = "CDATA" REQUIRED = "OPTIONAL">
   
The reason is that the possible choices are limited and work very well as 
enumerated attributes.  Note that this is what XML-Data does.  If you are 
defining some sort of XML-Data-Lite, XML-Data is probably a pretty good starting 
place.
