Comment/Wish 2: Additional "Approved" attribute associated with a
Selection element

In the 440-castvote (and other documents reflecting values from 440s),
the Selection element has an optional attribute named "Value" (and
depending on the resolution of one of my earlier comments, perhaps a
"Rating" attribute).

There are some "Rank-order with an Approval threshhold" voting methods
which allow a voter to express both a ranking AND approval/disapproval
of a candidate. To accommodate such a combination of voter
expressions, it is necessary to add another (optional) attribute to
the Selection element in the 440-castvote (and other documents
reflecting values from 440s). The new optional attribute (which might
be named "Approved") would be of type "YesNoType".

A proposed description of the "Approved" attribute would be:
Approved: An optional attribute which has the value "yes" if the voter
approves of the Candidate, has the value "no" if the voter disapproves
of the Candidate, and doesn't appear if the voter neither approves nor
disapproves of the candidate.
