Right. Turtle Patch treats it as a string. Other stuff in the RDF stack 
would break if one didn't at least follow obs-language-tag (SPARQL a 
'-'-sensitive  langmatches function and probably some UIs crack the'-'s) 
but nothing would treat a rigorous LanguageTag differently from an 
obs-language-tag.
