Re: updated editor's draft of the Geolocation API specification

It seems like there's a subtext here that "We have UAs that implement 
version $X of the spec, therefore version $X must be the final spec," 
even though there are still open issues with version $X.  While it's 
great that there are implementations, it's not so nice when 
implementations force things in or out of a consensus document.

I wonder if a more productive line of thinking might be to consider the 
current implementations as conforming to the *draft* Geolocation API, 
much like WiFi APs have been "Draft-N" for a while in anticipation of 
that standard.  That would give us the chance to work out some of these 
"V2" issues in the first rev.

The alternative, of course, is to explicitly agree that V1 is just going 
to be a documentation of what implementations are doing now, and reserve 
"what we really have consensus on" for V2.
