(c)there is any other alteration in what can be done by virtue of the right.

(3)A right of common which is registered in a register of town or village greens cannot at any time after the commencement of this section be varied so as to extend what can be done by virtue of the right.
(4)The variation of a right of common which is registered in a register of common land or town or village greens—
