I agree with Ron. I think we only get some simple mechanism. I think
that incorporating some other Specs like RDF will make our work
sompething else than simple.

I think we need a simple mechanism like this :

<ELEMENT NAME="FOO" >
        ...
        <METAINFO NAME="Icon" VALUE="c:\icon\foo.bmp"/>
        ...
</ELEMENT>

The DTD could be something like this :

<!ELEMENT METAINFO EMPTY>
<!ATTLIST METAINFO
NAME   CDATA REQUIRED
VALUE  CDATA REQUIRED >

Or something like this. Notice that name are only for exmple purpose,
and are definitively not a proposal.  

Other Element could be designed for providing informations about the
XSchema file (like revision, version, and so on).
