AtomPub accept

[Erik Wilde <dret@xxxxxxxxxxxx>]

hello.

we are working on an atompub implementation where we don't just want to 
limit the accepted entries to media types, but to certain subsets of 
documents (specifically, not just KML, but only KML with, for example, 
polygons, or only points). is there an established way of how to express 
these additional constraints in the service document? adding schema 
information? adding "profiles" (which probably would be opaque and 
specific to the service)? we can of course invent our own mechanism, but 
i am trying to find out whether there is something we can reuse.

thanks and kind regards,
