RDF concepts says that a language-tagged string has a lexical form (a 
UNICOD string), a datatype IRI (rdf:langString) and a language tag (a 
non-empty language tag as defined by [BCP47]. The language tag must be 
well-formed according to section 2.2.9 of [BCP47], and must be 
normalized to lowercase).

Anything else is not a language-tagged string. So, it's answer 1. There 
has been discussion about it, and I think this was what we came to agree 
on, but I don't remember if it has been reflected in a WG resolution.
