Leif, if you formally want @longdesc and @cite to be interpreted in RDFa, I think for the sake of the discussion in the RDFa WG you should really give a clear use case for both attributes' usage in terms of RDF triples. The mail of Shane seems to suggest that this would not really be a solution for assistive technologies, for example. B.t.w., you referred to my reference to object. The reason I referred to object is as follows. There are a number of attributes in HTML4 and HTML5 that might be reasonably interpreted in RDFa beyond @rel, @rev, @href. The original RDFa design decided to give a specific interpretation (essentially like @href) to @src to give a proper treatment to <img> (Luckily, the @src attribute covers the requirement of HTML5's <video> and <audio>.) With the same logic, the @data attribute of <object> could be interpreted a similar way but it isn't; I do not remember why it was decided not to do that, but I suspect the reason was to keep the language more succinct. That is why I would like to have a very clear use case both for @longdesc and @cite. And also why you do not add @alt to this list, although I think it would belong to the same family, so to say.
