I succeeded in getting wms:getFeatureInfo produce GML3 output from complex

However, I am now working on using HTML templates with getFeatureInfo.
I noticed in the code that processes templates, that it loads all features in
memory first.
However, it uses operations in the FeatureCollection that are not supported by
MappingFeatureCollection in app-schema.
What operations in FeatureCollection are not supported by
MappingFeatureCollection? Perhaps you want to take this to the geotools list if
it is a problem to be worked out?
But yeah; there should be no call to load everything at once; but even if the
code does do that - it should not effect your implementation of
FetaureCollection.

There is a whole series of methods not supported in
MappingFeatureCollection: anything that modifies the list (add, clear,
etc.) but the one used in the template code is "accepts" to support
visitors that visit all features. I think the reason is that a
MappingFeatureCollection doesn't actually hold any features, the
features are only created when you use the iterator.
I don't know if this should or can be worked out, because loading a
whole collection of complex features in memory just doesn't sound like a
good idea...
