but they're already there ya? so makes no difference what happens higher 
up the stack and what subset is implemented, surely this would simply 
allow some more innovation in different (future) serializations and 
syntaxes to be rdf valid.

[hoping I haven't failed to grok something here - I could atm have a 
boolean predicate in some doesn't yet exist serialization and it'd be 
valid at the rdf semantics level yes?]

ps: please nobody jump on this like we're talking about RDF/XML, Turtle 
or any serialization.
