I admit I am rather late in answering this message, i.e. it has
been posted 11.12.1998. But as far as I understood the 
archive no one else has answered it and so I'll give it a try.

If there is a structure A and an other structure B that may
occur as a part of A as well as on its own, one can model
A including it's part B in one DTD, i.e. "ainclb.dtd".
An instance of A that includes B looks like :
    <!DOCTYPE A PUBLIC "ainclb.dtd">
    <A> ... <B> ... </B> ... </A>

An instance of B not surrounded by A looks like :
    <!DOCTYPE B PUBLIC "ainclb.dtd">
    <B> ... </B>
