Re: proposed changes to the rdf:text document for option 5

One observation that might help (it helped me) was that the RDF terms  
'plain literal' and 'typed literal' refer to the syntactic forms. The  
phrase "typed literal" should therefore not be identified with the  
meaning "literal associated with a datatype" since there could be  
latters which use a different syntax, and therefore are not formers.  
And this is exactly what we have with rdf:PlainLIteral, the datatyoe:  
it is a datatype for RDF plain literals. So a plain literal is still a  
plain literal when this datatype is in use, but it is (then) a  
datatyped plain literal. Not, note, a typed literal. Typed literals  
with this datatype are illegal in RDF or SPARQL

Note also that this says nothing explicitly about values: it is purely  
a syntactic/datatyping issue.
