Dave, the only things I see being 'solved' by adding both or all of

to be yr point re: RDF/XML), but I don't agree that these alone have
started us down it.

Just FYI, I'm pretty sure I would formally object if "$" alone is
chosen. Hate to say that, but I think it's a bad (even if relatively
small) mistake.

I also find this confusing. I'd prefer commas in both places. iTQL
doesn't require commas between the parts of a triple, and I continue
to find that v. hard to read.
