Preliminary patch. xml:lang is a mapped attribute on all elements, so this function would need to take a namespace, or something else. For now I think we can just keep this but with a clearer name. Remove the NS_IMETHOD gunk while at it. Differential Revision: https://phabricator.services.mozilla.com/D322653
