Dear Ros

Regarding this requirement:

> 9.6 Where any auxiliary coordinate variable contains a missing value, all
> other coordinate, auxiliary coordinate and data values corresponding to that
> element should also contain missing values.

Appendix A notes that missing data is allowed in aux coord vars only in the
case of discrete sampling geometries. This means the checker could regard it as
an error also if it finds any missing data in aux coord vars, unless a valid
featureType att is present, arising from 9.6, in addition to the above.

However, I think the convention should be clear that this is not allowed except
for discrete sampling geometries, so I'll open a defect ticket for that.

Best wishes

Jonathan
