Why would it need to be modified? 

Envelopes are very simple conceptually and completely general---it
doesn't matter what your axes are and in what combination they come, if
you have data in some axis space, no matter what the axes mean, you can
define an envelope for that data.

Do remember however: 
        (1) Envelopes are not bounding 
        (2) the DirectPositions in the envelope have no intrinsic
        meaning, they are merely convenient informatic structure for the
        information.
