[Geowanking] locative packets

[Mike Liebhold]

Hi Jo, Schuyler,

Thanks for sharing this work.  I have only one question:

Why not include elevation as part of the core coordidinate descriptions?

e.g.

line 5:        <geo:elevation feet>128.25</geo:elevation feet>

Meters, of course, should be supported where appropriate.

While San Diego is mostly flat, where this wouldn't be absolutely 
necessary, there are some hills and knolls and multi-story buildings 
that someone might want to map or annotate. .And ideally,  this protocol 
will be  generally useful after ETCON, in places where elevation is an 
essential component of location.

Cheers-

Mike
