a=0 is not a boundary case; a=s is a boundary case. And no, I don't
think it's necessary - it doesn't change any of the activities.

Isn't that obvious?

It's there in writing for the special case. I'd rather say that t=a,
is equal to t=a,e - which is what I wrote.

It's not really up to us, but it's up to the UA. As the UA will have
to retrieve the full resource, the question is whether it wants to
retrieve the resource in byte ranges or in one go. I have formulated
this better in the spec actually.

I think they are all the same type and therefore don't need to be
listed explicitly.

Jack reviewing the spec/wiki page would be good.

Don't know.

Cheers,
