It seems that we will want to explicitly reference a CRS. Sounds like the micro-map guys are looking at Mercator, as WGS84 shows too high a slew for them to tolerate up north.

Thanks, Jens.

Yes, it is a great thing, which is why I asked for it to be included
in RFC5870 ;-)

It's important that we can refer unambiguously to, say, the locations
of features on The Moon, or the exploratory journeys of Mars landers.

I'm not familiar with GML, hence the question; it's good to know that
it allows for other CRSs.
