It is quite obvious as there is no specification about what to put there - ie no consensus was reached on the key part of what should have been reached. I argued against it in detail in that thread, and won't go over it here again. It's the dumbest idea I have seen in RDF spec land. I don't even know what other idea even comes close to it on the stupidity scale, as most other parts of RDF hold up extreemly well. > > - Steve Social Web Architect http://bblfish.net/
