Hi,

I've been looking at the definition of the "GEO" property in
draft-resnick-vcarddav-vcardrev-01. The current specification does not
clarify which datum and reference system is to be used for data in the
GEO property, which is really bad, and can lead to errors up to several
hundred meters (depending on which reference system is used).

I'd suggest clarifying that by adding something like "Coordinates used
in the GEO property MUST use the WGS 84 datum and reference system".
(WGS84 is the most common one, and also used in GPS devices).

cheers

Alex
