Getter for the builder's manifest definition

An intent lets the API know what kind of manifest to create. Intents are Create, Edit, or Update. This allows the API to check that you are doing the right thing. It can also do things for you, like add parent ingredients from the source asset and automatically add required c2pa.created or c2pa.opened actions. Create requires a DigitalSourceType. It is used for assets without a parent ingredient. Edit requires a parent ingredient and is used for most assets that are being edited. Update is a special case with many restrictions but is more compact than Edit.
