Saxon has a serialization format for arbitrary XDM sequences: you can see it
by running a query with -wrap option from the command line. Perhaps oddly,
Saxon can generate this format, but there are no tools to parse it and
reconstruct the original sequence.

I seem to remember someone proposing that a format like this should be
standardised in the XQuery WG years ago - if only as a standard way of
representing the results of queries in the test suite. But the fact that
no-one was prepared to do the work suggests that not many people thought it
was a big problem.

Not that I know of.

Yes. Whether the value would exceed the cost is anyone's guess.

W3C groups are generally having difficulty finding the resources to complete
their existing work programmes, without taking on anything new.

If there appeared to be sufficient support behind it, then yes.
