The widget type configuration does not hold a metamodel for accepted or required field definitions: this is an issue for Studio that sometimes need to
- fill default field definitions mapping (for listing widget types for instance)
- not fill any field definitions (for summary widget types for instance)
- fill field definitions according to bound schema field (for document widget types)
This is an issue also for some audio/video widget types that are presented on the summary, but still need a field definition mapping.
