Multiple occurrences of the same alternative are okay. The framework treats them as separate alternatives. Can't imagine the technical reasons on why the framework should force implementations to figure out if two alternatives are same and filter them out.

If implementers would like to optimize their implementations the framework does not preclude filtering multiple occurrences of the same alternative.

My understanding from the list discussion is that policies are *sets* of
alternatives, not bags, in that it does not matter how many times an
alternative appears, so long as it appears.

If so, then the blanket statement that "collection" means "unordered collection
with multiple occurrences allowed" is inappropriate.  If policies are allowed
to contain the same alternative multiple times, then someone has to say what
the differences is between, e.g., an alternative occurring once and the same
alternative occurring twice.

Conversely, if there is no difference, then say so explicitly.  That is,
instead of saying "A policy is a collection (unordered, multiples allowed) of
alternatives where multiplicity doesn't matter", say directly that "A policy is
a set of alternatives".
