Piero is right - what I said applies to the case that grid and CRS axes align -
which addresses the vast marjotiy of cases in my experience. However, OGC
coverages (to some extent CIS 1.0, more with CIS 1.1) can also address more
complex cases (irregular grids, grids embedded in higher-dimensional spaces,
grids given by sensor models, etc.), but naturally description of such grids
gets increasingly involved.
To put it differently: parameters omitted use defaults that try to keep usage
My 2 philosophical cents,
