On OpenTradingProtocol, we are using ID/IDREF in much this manner,
with the additional riders - IDs, once attached to an element, are
permanent because the entity may be authenticated (including
attributes) - and (the tough one) elements may be picked up from
several previous documents ("messages") and assembled in a new
document with a guarantee that the unchanged IDs will not conflict!

We only achieved this by clearly specifying the generation process for
the *content* of the IDs.

I think it was worth the effort, because it allows all the pieces of
the transaction to be readily accessible. It should even be possible
(although not required) to store all the components of an OTP
transaction (many messages) in a single document for receipt purposes
without the IDs conflicting.
