I know where I'd like them to figure.  RDF has two distinct 'layers' - Model
(i.e. abstract concepts) and Syntax (i.e. serialisation into characters that
conform to a particular XML grammar).

Check out the text diagram towards the end of one of my previous mails [1].
Given that data-typing is useful in general for defining extra validity
constraints, it does not seem unreasonable to want to specify more specific
data types for literals at the RDF Model layer.

It would also be nice to be able to validate RDF at both Model *and* Syntax
levels using both RDFS & XSchema (respectively) together.  Note that the
data typing for model and syntax layers converge - i.e. an int in the Model
is represented as an int in the sytax.
