Description

the interfaces defined in oak-core specify in some placed that the return
value will be null/false if the corresponding tree/property etc. does not
exist.

imo the api documentation should be extended state that this may also be the
case if the corresponding tree/property was not accessible to the editing content
session due to insufficient access permission.

this basically affects all methods on the Root and Tree interfaces including
Tree#getParent.
