Hi Dom,

I suspect that you are writing a document from the point of view that 
you are specifying the behaviour of software.  The RDF specs are written 
more from the point of view that they define the syntax and meaning of 
RDF documents.  This would explain why you might not find some of the 
things you expect.

Some more detailed answers below.

No.  We haven't defined a processing model.  That is something that 
could be done in the future, but we have deliberately stayed away from 
trying to define one as we've had enough to do already.

The RDF/XML syntax document defines what is and is not a legal RDF/XML 
document.  The concepts document defines and RDF graph, i.e. the 
abstract syntax for RDF.

No.  We have not defined classes of products nor their requirements.

I'm not sure what you mean by validating.  RDF defines no concept of 
validation.  The schema document explains that schema can be used for 
inference, or can be used for detecting errors in documents, but it does 
not mandate either use.

If you mean character encodings, No.

I'm not sure what you mean by that one.
