I guess you mean that the actual object type itself would provide the
metadata, much like the meta_type property of a Product?  This helps
to an extent, but you'd end up needing a huge amount of nearly
identical products to support all the types you'd require.  

I think Michael's suggestion is probably the most realistic in my
context, combined with enforcing some metadata through workflows where
practical.  

Interestingly, this is a problem that has apparently been discussed
elsewhere.  Take a look at this post to the IETF WebDAV newsgroup, for
example, in which a 'Properties Requested' response is suggested:
