Please don't be surprised -- depending on how new a suggestion is,
sometimes I like to sit back and hear different people's opinions for
a few hours or a few days before blurting out my own.  On this topic,
I'm a little uncomfortable putting in a core feature for catalogues
when XML catalogue formats haven't settled yet (likewise, I don't
include a feature for data typing, though some kind of data typing
will undoubtedly arrive before long).

It would probably make more sense for the promoters of different
catalogue formats to define their own properties and/or features, such 
as

  http://www.oasis.org/sax/features/entity-catalog

That way, we won't have any unpleasant surprises when a user expects a
parser to use one type of catalogue and the parser finds another
instead.


All the best,


David
