    77All responses will highlight the `domainSet` of each [http://schemas.opengis.net/gmlcov/1.0/coverage.xsd coverage], which will all translate to some [http://www.schemacentral.com/sc/niem21/e-gml32_Grid.html gml:Grid] rectified or referenceable subtype.
    88We will assume that warped grid will be described via `ReferenceableGridByArray`, although an alternative description via origin, offset vectors and matrices of coefficients is also possible.
    9 In case of mixed rectilinear/curvilinear geometries, a non-standard so-called `ReferenceableGridByArrayAndVectors` type ![1] will be used, for a more compact and convenient GML description.

     9In case of mixed rectilinear/curvilinear geometries, a non-standard so-called `ReferenceableGridByArrayAndVectors` type ![1] will be used, for a more compact and convenient GML description. Coefficients in a `ReferenceableGridByVector` are also kept optional, to allow mixing of regularly and irregularly spaced axis in a same geometry (see again ![1]).
     10
     11When determining which CRS type should be bound to a certain coverage, the term `SpatialCRS` will mean any Earth or Planetary (or Image) related CRS, like `VerticalCRS`, `GeographicCRS`, `ProjectedCRS`, etc. See GML 3.2.1 (OGC 07-036) for more info on the available CRS types.
    1212
    1313Finally, we will assume that all the time series will be referenced by the daily-resolution (UoM=days ['''d''']) [http://kahlua.eecs.jacobs-university.de:8080/def/crs/OGC/0.1/ANSI-Date ANSI-Date] CRS along the temporal dimension, which (by default) has a '''`t`''' positive-onwards axis.
