David, thanks for replying!

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

Any reference to this ? 
I've plotted out a course for this but not sure if its the right track:

http://xml.calldei.com/XDMSerialize

I have seen nothing similar ... but would love to.

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.

Again, any references ? I havent seen any hints of support for XDM as the
input for XQuery or XSLT ...
(say a sequence ...)

Join the WG ... any suggestions on how to Join W3C unless my employeer has
deep pockets ?

Agreed.

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

Reference ? How ?
