Never two but three - I'd like to offer LLI (Locally Linked Infosets) 
[1] - a function-based approach to accessing post-validation results 
which could, I think, be used to implement the Schemachine.

The design aims of LLI are to be:

    Simple  - The proposed solution should have few components, and 
should be straightforward to understand and use.
    Harmless - The solution should have little or no impact on existing 
technical standards or conceptual models.
    Open  - Both XSDL and its alternatives should be treated as 
first-class citizens
    Consumer Oriented - The document consumer should choose which schema 
engine(s) and schema(s) are used to validate the document or any of its 
parts.
    Flexible - The proposal should permit the use of multiple schemas or 
schema engines for the same document or elements, either independently 
(in parallel) or cumulatively (in sequence).
    Pervasive - Should be easy to implement, and it should be possible 
to access it from environments that supports XPath, such as XSLT or the 
DOM.

I hope it proves useful.

Francis.
