[xacml] New issue#2 from "Boolean Policy resolution"

[Anne Anderson <Anne.Anderson@Sun.com>]

PM-1-?: result of <N-OF n=0> combinator expression

We all agreed that <N-OF n=[something greater than 0]> was an
error if there were not at least n predicates to be evaluated.
We also agreed that the semantics of <N-OF> were "at least n
of".  We did not agree on what should be the result of <N-OF
n=0>.

Potential Resolution:

<N-OF n=0> results in TRUE, regardless of the results of the
predicates in the combinator expression.

Champion: Anne
