Which would be the canonical way of getting the language of a content object in a browserview?
I’m using plone app.multilingual and it looks like there are two options:
language = obj.Language()
with the caveat "All content objects don’t necessarily support the Language() look-up defined by the IDublinCore interface."
or using the interface/adapter in CMFPlone.interfaces
language = ILanguage(obj).get_language()
