Whilst your wording there is unclear, I hope you're not stating that URIs
plus fragments necessarily identify some subset of resources or - worse
still - some series of characters/bytes. RFC 2396 is quite clear (or quite
vague depending on how you look at it) by stating:-

   [...] the format and interpretation of fragment identifiers is
   dependent on the media type [RFC2046] of the retrieval
]]] - http://www.ietf.org/rfc/rfc2396.txt

As far as I can discern from the RFC, it does not give any constraints as
to the interpretation of the fragment identifiers given above. It defers
the interpretation (and therefore the constraints upon the semantics) of
the fragment and that which it identifies to the media type specification.

Practically, rdf:ID would be a total disaster if chunks of documents were
the only things that could be referenced by fragment identifers.
