Resolutions
  1. The datatype previously known as rdf:text should be called rdf:PlainLiteral link
  2. The title will no longer mention i18n. It will be something more like: A Datatype for RDF Plain Literals link
  3. Pending approval from Michael Sperberg-McQueen, we'll remove the 3rd intro paragraph (from LC version). It talks about xml:lang, etc. If he does't approve we'll keep it, with some reluctance. link
  4. rdf:PlainLiterals will map 1-1 to RDF Plain Literals, so Plain Literals with and without language are both handled by rdf:PlainLiteral. link
