From the spec:

model_template - Used to reference a template or cla.... When there is no applicable model template for a given model type (i.e. model_type=virtual) it is assigned a value of NULL.

I can't find it explicitly in the spec of HDF5 but if you try to save None to an HDF5 dataset, it will be saved as an empty string. My question is there an agreement on how to represent NULL values in SONATA?

Raise an error in case CellCollection contains None or np.nan value.

Because HDF5 does not have a value for NULL, we can't save such values.
Upon saving None is saved as '' which is not correct. See
AllenInstitute/sonata#122 for discussion.
