I think we anticipate a fixed set of rules, very close to the rules
in the XML 1.0 document, and then: whatever Unicode says is in, is in,
and whatever is out, is out.

But in full generality that means each document has to bear the
version number of Unicode that it assumes (for its names only, of
of course, not for its character content).  That means a series of
updates to parsers are required, and control of the schedule is
lost from W3C to Unicode.  Is this a Good Thing or a Bad Thing?

Just so.

Some parsers, at least, have their own tables.

That's dangerous: it leads to interop failures.  What if the version of
Java at the receiving end has slightly different tables from the one
at the sending end?

But that point has to do with *implementation*, not specification.
