Hi Mikael,

Yes, you will see from my comment on the PR that I had come to the
same conclusion. However, rather than take PR62044 as a place holder,
I will open a new PR. Thanks for the information about the derived
type namespaces. Originally they were added with precisely this in
mind (and in fact?) but they seem to have fallen into disuse (or
not!).

Cheers

Paul
