def can_update_relationships(self):
return True<EOL>
Tests if this user can update ``Relationships``.

        A return of true does not guarantee successful authorization. A
        return of false indicates that it is known updating a
        ``Relationship`` will result in a ``PermissionDenied``. This is
        intended as a hint to an application that may opt not to offer
        update operations to an unauthorized user.

        return: (boolean) - ``false`` if ``Relationship`` modification
                is not authorized, ``true`` otherwise
        *compliance: mandatory -- This method must be implemented.*
