As I was adding Data Model Validators to my Models, I noticed:
validators are added as a childnode of the model
the name of a validator (as visible in the inspector) cannot be changed
On each added validator, the property 'field' has to be set. Would it be an idea to move the validators in de projectinspector to appear as a childnode of the modelfield? On adding a validator to a modelfield, the property 'field' can then be set automatically (actually, the property can probably be removed). Using this approach, a custom name for the validator is no longer necessarily: it would suffice to show the type of validator in the inspector.
