[Bug]: MatNWB does not enforce quantity for groups of a wrapper/interface neurodata type

[ehennestad]

What happened?

The following should fail (but does not).

The NWB schema specifies that ImageSegmentation should contain at least one PlaneSegmentation object. The following code demonstrates that it is possible to export an ImageSegmentation object without adding a PlaneSegmentation to it.

Steps to Reproduce

nwb = tests.factory.NWBFile();

ophys_module = types.core.ProcessingModule( ...
    'description', 'Contains optical physiology data');
nwb.processing.set('ophys', ophys_module);

img_seg = types.core.ImageSegmentation();
ophys_module.nwbdatainterface.set('ImageSegmentation', img_seg);
nwbExport(nwb, "temp.nwb")
