    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.
     8We 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.
    89In 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.

    1013Finally, 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.

    66 This section covers time series of point observations with no spatial reference (or where the spatial reference was not considered relevant): in this case the only distinction is whether there is a regular time step between observations, or not. In its degenerate case, the series turns to a [#a1a single point].
