So it is impossible to, for example, talk about the class of their values, to restrict queries to them, etc.. This problem - of literals with no type - was one the motivations for rdf:PlainLiteral in the first place. The new proposal takes some plain literals (without tags) and assimilates them to xsd;string, which cannot (for XSD reasons external to RDF) accept the values of tagged literals. So we need a type for those values, which are found nowhere else in RDF and need a home, and cannot be banned because i18n and Reuters, among others, want them.
