* `action`: Determines whether or not a given action is allowable. The candidate
argument here is an Action; the context is its action context object.
* `composition`: Determines whether or not domain objects of a given type (first argument, `parentType`) can contain a given object (second argument, `child`).
* `composition`: Determines whether or not a given domain object(first argument, `parent`) can contain a candidate child object (second argument, `child`).
* `view`: Determines whether or not a view is applicable for a domain object.
The candidate argument is the view's extension definition; the context argument
is the `DomainObject` to be viewed.
