Never two but three - I'd like to offer LLI (Locally Linked Infosets)
 - 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
Consumer Oriented - The document consumer should choose which schema
engine(s) and schema(s) are used to validate the document or any of its
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
I hope it proves useful.
