Personally I'd say "no" due to the lang tag issues.

Ish. A plain literal without a lang tag is equivalent to an XML string literal.

The trouble is that xml:lang is not meaningful for xsd:string. So if you 
want people to be able to use xml:lang in their labels they have to use 
either plain literal or full XMLLiterals.
