Ok, so taking a conrete case, a "document" file type with hit type "contact"
could be a vcard stored somewhere on disk?

It took my a sec to grok the distinction between hit type and file type. If
I understand correctly hit type could also be called "present as", and yes
present-as and file-type are independent the way you describe it. However
this is not the way I would abstract things. I think a category tree like
http://www.grillbar.org/xesam/object-graph.png would be more natural. In
this way both MailAttachment and files in a tarball are both EmbeddedObjects
in a natural way.

Cheers,
Mikkel
