no, it actually isn't. We assume it's WGS84 - as it's the most common
CRS and the one everyone is moving towards, that's the safest way
forward considering what I say next.

yeah Ray, but he isn't writing a bis that adds the concept of
versioning the second time around.

If this were (time-machine alert) 2004, then this should have been
written into 3825. I agree. But it's not 2004 -- and we shouldn't
knowingly reduce the number of clients that get location they will
keep without having the ability to inform anyone/thing there's a
problem. Not when it affects emergency calling, which we all know
your stance will affect it adversely.

wow -- that's quality Monday morning quarterbacking 5 years later.

Do you really want me to go through all your RFCs and point out
everything you missed as "sloppy specification design" on a public
(worldwide) list?

I can - but oh... that's right, you haven't written any RFCs
according to http://www.rfc-editor.org/rfcsearch.html

Perhaps you shouldn't make you attacks so personal until you've
written your own RFCs for others to thrash.
