Re: [Geopriv] Consensus request: Relative location and encoding options

Martin - <this is exhausting>

I could respond to each individual issue or point below but I see no point.

This proposal was submitted to specifically resolve a request from the IEEE
and Option B solves that request. This proposal should have moved on months
ago.

When we discussed this in the design team previously there was consensus on
Option B except for you.

I'm not sure why you or I are speaking up on this issue given that the
purpose of sharing with the larger group was to hear other opinions. We
already know ours.
