Basically, the author needs to write up a DTD (or download/refer to one)
which includes all the tags used in that document. This could be based on
a modular DTD with appropriate elements defined for extensions, including
extensions to the style/semantics program that accompanies the DTD. I'm
still not sure after reading about DSSSL, but the author may be able to
extend an existing stylesheet from another (to support more tags.) The 
exact syntax might be a bit hairy, especially with a modular DTD, but it 
is theoretically possible. An extended CSS might even be made to serve as 
a semantics language for simple hypertext document types.
