UML/XML specs

[Owen Cliffe]

Does anybody know if there is an XML Document Type specification for
representing UML Data dictionaries etc (not neccesarily the diagrams)?

something like 
<CLASS name="blargh">
        <INHERIT name="Super"/>
        <MEMBER name="foo" returntype="int">
                <PARAM name="p1" type="char"/>
                <PARAM name="p2" type="char"/>
        </MEMBER>
</CLASS>

and other UML things, or does the UML spec only deal with drawing pretty
diagrams?
