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.
