Assuming the introduction of geo:lat and geo:lng, I think this means that an application that provides lats and longs calculated in an older datum (e.g. one of the old Australian ones that are up to 200 metres off WGS84) would need to be rewritten to convert its lats/longs to WGS84 before sending?

I don't know how many systems still rely on an older reference ellipsoid, but I figured it might be worth a comment. Sending specimen data verbatim would be problematic here.
