I always see two-letter ISO-639-1 language codes. This isn't enough,
not all languages have them.
Does the spec specifically call for these, or does it also allow for -3?

RDF 1.1 Concepts:
http://www.w3.org/TR/rdf11-concepts/#section-Graph-Literal
so it's BCP 47 / RFC 5646
The grammars do not include the RFC grammar (because a big language tag
grammar would dwarf the rest).
http://www.w3.org/TR/turtle/#grammar-production-LANGTAG
[144s] LANGTAG ::= '@' [a-zA-Z]+ ('-' [a-zA-Z0-9]+)*
So neutral and the grammars provide a more general match to language codes.
Jena has a language tag parser: LangTag.
