Hi Ben
The mandate of my customer is to implement this feature for WMS on a
service level. Perhaps I can convince my customer to implement it at a
layer level, using the configuration of the service as a default.
At the moment, there is no plan for implementing restricted MIME types for
WFS. Would be nice to have but it is a matter of funding. (As always).
Sorry for the bad news
Cheers
Christian
