Isn't the thing about RDF 2.0 that it is for later.

I see our job as:
- clarifying what is already out there
- not closing doors for RDF 2.0


So we have two different opinions about what RDF 2.0 might be like, this
helps in that we use this to inform us as what NOT to do, rather than
what to do.

We shouldn't solve any problems in ways that prevents RDF 2.0 from
either:
+ imposing another level of indirection as the general literal
representaion
or
+ moving to rich typed literals as the general literal representation


My view is that M&S is clear that Literals are just strings (with that
lang thing!) and that we can get a long way, (far enough), with sticking
to that.

I also think that RDF 2.0 does need to say something more.

Our charter says ...

A major reworking of types into the Graph and Syntax is in my view out
of charter. I think we either can rubber stamp DAML use of XML schema
datatypes or finish off RDF 1.0 as untyped and ask for a new charter to
do types in RDF 2.0.
