Some minor issues with OME-XML consistency/correctness:
BPAE-cells_mitosis_3chZ(WF).czi ome-xml has FilterSet and Dichroic elements but these are not linked to internally in the ome-xml structure other than from some of the original metadata elements (and these are not true refs).
Mouse_kidney_VivaTome-1chTZ.czi: RefractiveIndex is "NaN" which isn't looking right. Likewise for PinholeSize.
Testimage_SYS169_CZMicroscopy.czi: LensNA is "-1.0". While this is possible for some materials, it's not that common in microscope objectives TTBOMK unless this is some fancy system with superlenses, so I just wanted to query its correctness. Same issues with FilterSet/Filter/Dichroic as above being defined but not linked.
Not related directly to the PR, but the space wastage from the XMLAnnotation blocks is far too much when you end up with several thousand annotations. It would be nice if key-value annotations could be stored in a single block, maybe with a uniqueness constraint on the keys.
