tions and no normative processing model for extensions is
        defined. Accordingly, implementations that rely too heavily on
        the use of extensions may experience reduced interoperability with
        other implementations.

        For extensions, [[JSON-LD]] is used as the primary mechanism for
        defining and disambiguating extensions. Implementations that wish to
        fully support extensions SHOULD use [[JSON-LD]] mechanisms.
