Comment (by jonathan):
Dear Martin
Thanks for this initiative.
I don't think the statements are contradictory in 9.1 that certain space-
time coordinates are mandatory and in 9.2 that a size-one instance
dimension can be omitted, because the instance dimension is not a
spatiotemporal dimension - it is just an index running over the collection
of features. The mandatory space-time coordinates are for the individual
single features in Table 9.1. The idea is that the feature types are
distinguished by which sort of spatiotemporal coordinate they must have
and are allowed to have. However, if the document is unclear, it should
certainly be clarified.
It would be good to add new feature types that are distinguishable in
these terms from the existing ones, provided that these new types are
required in practice i.e. there are present use-cases for them. This would
follow our general practice that we only add to the convention when there
is a need, rather than anticipating possible needs.
Best wishes
Jonathan
