    26 The result of a WCS Core subsetting may not be a grid (ie, array) any more.
     26The result of a WCS Core subsetting may not be a grid (ie, array) any more.
     27However, the result of a subsetting, as per Core, of a gridded coverage should result in a gridded coverage again.
     28This situation can occur if the coverage's domain grid establish axes irregular or warped or rotated wrt. the Native CRS axes.

     30'''Definition:'''
     31 * '''Domain Grid''' = the grid established by the points of the domain set as expressed in the coverage's Native CRS. For Grid Coverages, this is a grid by construction.

     33'''Observations:'''
    2934 * we believe that the origin of a coverage does not need to be inside array (as per GML 3.3)
    3035 * trimming (and slicing?) generate grids where some points need to be existent for reasons of toppology, but do not have any meaning (nor in value, nor do they have a a valid geo position)
