I wouldn't be as optimistic as Jeremy, but we (well me) might produce
another team or member submission doc that might be closer.

That's the longest comment and I was aware of it.

It does address several flaws in the document, but implementors don't
seem to have had too much problem using the test cases to figure it out.

Formally, I don't think a WG has to take into account pre-WG document
comments, although it would be reasonable for the same comments to be made.

I've consolidated the issues I've got from my inbox, comments and elsewhere
(IRC) into an issues list.  That github repo also has the turtle spec
history and tests.


(might improve the layout, I'm new to Markdown)

and then I might make a new version there if I have the energy. It's
more likely I'll do this before any new WG appears, I would guess.
