Child Permissions Property

Points from a Permission on this Thing to the one to check for its children. -- Collection: Optional Type: Thing Type

There are a small number of Permissions (as of this writing, only Who Can Edit), which are split into one Property that you check on this specific Thing, and a related one that you check for its instances. For example, Who Can Edit, on a Model, says who can edit the Model itself; Who Can Edit Children on that Model says who can edit the "children" (usually the Instances) of that Model. In such cases, this meta-Property points from, eg, Who Can Edit to Who Can Edit Children.

This approach is a bit over-elaborate, and might yet evolve a bit. But for now, make sure to keep this different in mind.
