Bunch of other objectives as well that preclude the whole thing being a single document ... such as incremental generation (aka log file or long running source),  
support for large documents (streaming  of various flavors), simple concatenation etc.
And yes per-item markup of some sort is needed.

I have pretty much worked it out here but it's not entirely satisfying.
The biggest issue now is what parts of XDM I want to sacrifice as I can't have *everything* ... things like node identity are hard,
user defined types require access to an in-scope XSD, base-uri requires some additional markup etc.
So by not having everything I can't satisfy everyone (even myself ).

So my evolving goal (not yet updated in this document:  http://xml.calldei.com/XDMSerialize 
 - I have 8 distinct use  cases so far )  is to cut back on the fidelity  and aim for more usability,
in particular streaming, log files, and getting basic XDM typed data across applications which I feel is a high value ...
