16   Developer Note:
17   The order of the enum entries is significant, as it corresponds to the canonical numbering
18   of DOFs, and the fact that the numbering starts at 0 may also be used by the implementation.
19 
20   Fortran Note:
21   Currently there is no Fortran support, it could be easily added.

60   Data structure (C struct), analogous to describing a degree of freedom associated with a `DMSTAG` object,
61   in terms of a global element index in each of up to three directions, a "location" as defined by `DMStagStencilLocation`,

67   The component (c) field must always be set, even if there is a single component at a given location (in which case c should be set to 0).
