Feroz, Ghislain,

Since the CG has not yet taken any decision on use cases, our proposal
is to leave any member free to add his/her own, after having sent a
summary to the CG. Of course, before proposing a separate use case, it
is important to consider the possibility of merging it with existing
and possibly overlapping use cases, whenever appropriate.

Unless the CG disagrees with this approach, we would then give Feroz
the green light to add the PAT use case.

@Frans, we also wonder whether you have a use case to propose. Some
time ago, you raised an issue on the representation of SRS/CRSs in
coordinate geometries.

Cheers,

Andrea and Michael
