There is no resolution, so there is no objection yet from my point of view.

I'm not sure Conrad agrees on that. Do you Conrad?

We had a lot of discussion about that today, and in particular the fact 
that Content-Range-Equivalent will not solve your problem either. I 
suggest we do a summary of this discussion tomorrow morning on the phone.

> Incidentally, I have a few more questions on that resolution:

In the URL, we still have to figure out if we use comma or semi-colon.
In the headers, what would you use if not comma?

Yes, we never say the contrary. And actually, what we said today is that 
for the spatial track, it will most likely happen on the client, and if 
it needs to go to the server, it will be better handled by the query 
parameter.
Cheers.
