  I have got the following Request For Enhancement 
    http://bugzilla.gnome.org/show_bug.cgi?id=125266
the idea growing up seems to have the association done at the toolkit
level instead of having it into the instance.
IMHO it's quite cleaner, the author can't really know what are the 
acceptance rule a given instance will go though, but on the other hand
at a tool level automating the association between the instance and the
schemas simplifies things a lot with the associated results (relibility,
cost of maintainance, etc ...)

 Ideally having a predefined (standardized) vocabulary to match the
instances to Schemas (or processing rules but this is yet another can
of worms) would be the best way to attack this problem. It's unclear
to me whether the approach taken by nXML can really be expanded to other
frameworks, I need to read and digest the proposal first,
