For contrast,

- radio buttons: a group of options where only one can be specified (mutually 
exclusive)
- check boxes:   a group of options that are independent of each other (any 
number of
                   them may be specified)

- ???: a group of options where, if one is specified, all must be specified 
(mutually
         inclusive)

Given that radio buttons and check boxes are all effectively
using boolean states, doesn't this mean none of the group
or all of the group?

In which case it's a single boolean value - a check box that
controls all options.

I suspect I'm missing something...


radio buttons (none or one):

   t-shirt size:  Small  Medium  Large


check boxes (none or one or several or all):

   sandwich toppings:  lettuce  tomato  onion  cheese


entangled (none or all):

   image size override:  height   width
