mutli-language serialization (POSTing fields with different languages)
Currently I can POST the resource, and the language will be derived from the Accept-Language
header, or from the @language
set on the value-object submitted
However I may want to submit a multi-language request, with different languages for each field. I've not tested yet if this would result in the content being submitted correctly (with the different languages), but certainly the response would be serialized in only one language
