Help, tied up by the chain

[Ruan Strydom]

I need additional info for elements in DTD so what I have done was created a 
class ElementDeclaration extending ClassDeclaration (and the data classes).

ElementDeclarationData has the following members:
    KDevelop::IndexedString contentType;
    bool openTagRequired;
    bool closeTagRequired;

The problem is that the parser now depends on this, as I need to use DTD 
(parsed and built before SGML) to correctly parse SGML. So I have a recursive 
dependency. In addition to this, all new libs that use the DUChain for SGML 
will now have a dependency on the SGML DUChain lib. And I need to expose the 
headers. Also now the DUChain is not as nicely abstracted anymore.

Should I collapse the dependency tree and make the parser and duchain one lib 
or is there another way of storing this info so that it accessible using the 
abstract classes only? 

ps: If the enum uses where int's or if C++ allowed extending enums I could 
have used some of the existing members.

Let me know if I should commit the code/changes and point you to the problem  
area.

Thanks
