I don't think the PSVI people need for normal implementations would include
these things. The current PSVI is really at the wrong level of abstraction.

Say what? That would be insane!
But there is an implementation that comes close, and also serializes the
results as XML - Richard Tobin's XSV. Here's documentation for the
serialization format:
A schema for serialized infosets
Richard Tobin and Henry Thompson, LTG, University of Edinburgh
http://www.w3.org/2001/05/serialized-infoset-schema.html
But please, let's not just ape that.
For a much more minimal set of operations, it's worth looking at this:
Document Object Model (DOM) Level 3 Abstract Schemas and Load and Save
Specification
Version 1.0
W3C Working Draft 14 February 2002
http://www.w3.org/2002/02/WD-DOM-Level-3-ASLS-SaintValentin/
Particularly this
part:
http://www.w3.org/2002/02/WD-DOM-Level-3-ASLS-SaintValentin/abstract-schemas.html
There are three more that may or may not have been publicly announced, two
from companies you are probably familiar with. I have no idea whether these
companies want to go public. W3C members can see the relevant information here:
http://www.w3.org/XML/Group/Schemas.html
These are the ones I find particularly interesting. Anybody know public
information on these?
