Why is optical channel not a link in ImagingPlane?

[ehennestad]

Let's say I have a multichannel, multiplane (multiple depths) two-photon recording. For each ImagingPlane I would use the same optical channel but following the schema I need to add duplicated instances of the OpticalChannel to each imaging plane at different depths

This is one of several things about the ophys schemas being improved in the ndx-microscopy extension which is then planned to then be submitted to the TAB for approval to be integrated into the core here

The ndx-multichannel-volume extension for multichannel multiplane imaging should also support this.

Thanks for clarifications!
