I need an type-augmented infoset. I'd like to obtain schema information in
an abstract grammar format, independent of the schema language used. An
important thing would be the ability to obtain the name of the type
associated to any given element (this name could be precised in a RELAX NG
annotation). This way I could use a validator to disambiguate the type of
each XML element and use this type name to process XML data in an extensible
way.
So OK, relying on XSD PSVI is bad, but typing info as part of the PSVI is
good.
