I agree that many folks wouldn't understand how to use a more advanced
location system.  Many folks won't understand how to use a simple one,
either.

There are many ways of specifying celestial locations, otherwise we would
never locate anything again once we found it.  They are more complex than
most coordinate systems though.  Common celestial formats use 8 or more
dimensions of coordinates for the object.  I have done a bit of  programming
for celestial (satellites, solar objects, stars, etc.) tracking programs.

Seems fairly clear to me.  The only thing I find slightly ambiguous is why
it is limited to Earth.  I only was bringing up the point that it is limited
to the Earth in its usefulness.  And, there are many resources that would
benefit from this form of system which are outside the Earth.  If limiting
it to the Earth, in the hope of simplicity, is a goal then that is
acceptable.  If limiting it to Earth because no one would want to specify a
resource outside Earth is a goal, then that is not acceptable.  Seems a
trivial distinction but not if you look at the history so many other
web-related drafts and specifications.

That is explicitly stated and quite clear.

Again, seems quite clear to me.

Sounds like a good idea.  I don't know how many times I have wanted to
transfer location data between applications and had to copy and paste.
