Folks, I have finally put up a very rough document - still more like a skeleton than anything else. It contains modified versions of David Meredith's text and is available at: http://forge.gridforum.org/sf/go/doc15764?nav=1 I would like to keep the token for a little bit longer before passing it on to someone else. I would like to note that this document, being the zeroth iteration, does not have any group consesus as yet. Would like this to become a strawman once complete for the extensions that are being proposed.
