[Proj4j] Re: Proj4j Digest, Vol 5, Issue 1

[Martin Davis]

Yes, I think it's the test file in the main MetaCRS SVN that's causing 
the problem.

Fixing that file would be great - it would be nice if Proj4J could 
correctly execute the MetaCRS tests!

Or - an indication of ordinate order needs to be added to the test file 
format.  I think we had this discussion a while ago...  IIRC, you were 
in favour of having this indication, and I wasn't at the time.  Hoist by 
my own petard!
