Maybe, whatever, it was just an example. In both cases, it makes a valid 
and consistent RDF Graph. Then it's all a matter of having the right 
datatype map in the application.

Use? What do you mean? I can put it on the Web, it validates, I can do 
RDFS reasoning with it, etc. But to be useful, you'd need to to do 
something specific in your application to deal with these special literals.
But if you don't care about quoted graphs, it's not causing 
interoperability breakage as it's valid, good'old RDF.

Yes, the syntax is not really practical.
