I have believed something like this would make the best solution.  I 
think it needs working out though. For example, would the type hierarchy 
work to express the structured nature of language tags?  Using ""@en as 
the syntax form gives compatibility.

For this WG, I prefer to leave this possibility open and simply convert 
xsd:string's simple literals as in the original proposal.
