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?
