I think (Rich Salz notwithstanding) EXI 2 may do this. Remains to be
seen, but I hope so.

I'm not sure on the status of this; the first part is already there I
think, unless you're asking for a further relaxing of constraints in the
XDM - in which case please file a comment against the last call draft of
the XDM 3.0 that was published in December; the Status section of the
document has a link to the Bugzilla instance for doing that.

As for implementations - can you think of ways we could test it? if so,
feel free to contribute tests, or to join the WG :-) or just to bug the
vendors.

Agreed.

Not sure if this is premature, but it may fall under your No, 3 above.

Well, that would be nice. It'd have to offer a business advantage - one
or more of
. faster
. lower cost
. enabling (things you couldn't do before)

Thanks for the feedback!
