I brought up this issue to the Coverages WG in St Louis when I
co-presented with Ben. I was told that the CRS variability was resolved
with parameterized CRSs via URN. I also brought up the issue of
pressure levels, and it sounded like pressure levels were representable
as well. I also have a note about ISO 19133 and Linear Coordinate
Reference Systems, which is probably in reference to the representation
of pressure levels.
I believe George Percivall and Carl Reed answered these questions, so
they may be worth contacting for further information.
