The objection there is that this would add *more* exceptions to the design of RDF literals (where our goal was to make the handling of literals more uniform), and also rdf:HTML doesn't need it because it already has a mechanism for language annotation (<span lang="xx">). > > Best, > Richard I would be, actually, a little bit stronger than Richard on this one. I think it would be wrong to add a language tag to HTML (or to XML, for that matter): having two different tools (the XML/HTML provided tools as well as an RDF provided tool) would lead to confusion. Eg, when comparing two HTML literals (which is based on a DOM function), one where the language tag is set by RDF and the other where the language tag is set via the HTML attribute, would two such HTML literals be equal? (Provided the rest of the DOM is identical.)
