RE: RE: [Geopriv] More on the contents of the Location header URI- http

What it means is that you MUST provide a Get mechanism with no
parameters, you MAY provide anything you like on top of that. If you are
prepared to take the hit with trying something specific first then that
is your prerogative, or you may decide to do the GET first, and
something special as a second-try, which is also okay. I simply don't
agree with your reasoning to exclude a simple GET mechanism now.
