/// extension types that are not recognized by other implementations. Care should be taken to not
/// unduly overlap with or duplicate the existing Actor types.
///
/// When an implementation uses an extension type that overlaps with a core vocabulary type, the
/// implementation MUST also specify the core vocabulary type. For instance, some vocabularies
/// (e.g. VCard) define their own types for describing people. An implementation that wishes, for
/// example, to use a vcard:Individual as an Actor MUST also identify that Actor as a Person.
