So someone should file an issue on this. It should be possible to specify the language of an invisible element.
If not for the Microdata spec, then at least for the Microdata-to-RDF extraction, where language tags are a first-class citizen.

In all GoodRelations examples, we use datatyping, except for xsd:string, because while this is theoretically needed, too, the distinction between plain literals and typed RDF literals with xsd:string as their type is hard to explain to practitioners.
