[security-services] Multiple Actions in AuthorizationDecisionQuery

This issue is similar to ISSUE:[DS-11-05: MultipleActions] and
ISSUE:[DS-11-01: MultipleSubjectAssertions], and it must be solved.

1024 The <AuthorizationDecisionQuery> element is used to make the query $B!H(BShould these 
1025 actions on this resource be allowed for this subject, given this evidence?$B!I(B The response will be in 
     *******
1026 the form of an assertion containing an authorization decision statement. 
                                         ***********************************

How the PDP should respond if some actions are allowed and others are
not?
(Default value of <RespondWith> element is "SingleStatement".)

Thanks,
Toshi
