[xacml-comment] equality & set/bag functions

[Seth Proctor <seth.proctor@sun.com>]

The set and bag functions (along with others), are defined as type-[name]
where this is expanded to include one function for each standard type.
Presumably this includes the two duration attribute types. One of the bag
functions and several of the set functions also specify that their
definitions are based on using the type-equal function for the coresponding
type. The equality functions, however, are defined individually for each
type, and no equal functions are defined for the two duration types.

So, the question: should there be equality functions defined for the two
duration types, or should certain type-[name] functions not be able to
handle the two duration types? It seems like one of those two must change
to make this work.
