The charter constraint didn't seem to bother us that
much in the case of aboutEach and such. (though
there was some action to check with the SemWeb CG
whether it was OK, and I'm not sure what, if anything,
ever became of that.)

How do you come to that conclusion?

The only way to find out for sure that you need another
last call is to ask to proceed to the next step and
get turned down.

I suggest that removing it in the course of moving
to CR/PR would be welcomed by reviewers and implementors.

There's an argument to be made that a last call is in
order so that anybody who's using it has a chance
to say "hey! I wanted that! put it back!" But it's
not a black-and-white issue. If, as you say, we
know bagID isn't used, then there's little reason
to do a last call.

I think you can stop there.

That question seems separable.

Or perhaps you're saying that it's your considered
opinion that the WG should do another last call if
it removes bagID?

Yes, the implementors understand and were convinced that it's
worth implementing.

I think TimBL has raised an interesting question as to whether
the users understand what they're saying when they use this
