        public Collection<org.ow2.authzforce.core.pdp.api.PepActionAttributeAssignment<?>> evaluate​(org.ow2.authzforce.core.pdp.api.EvaluationContext context,
                                                                                            Optional<org.ow2.authzforce.core.pdp.api.EvaluationContext> mdpContext)

        Evaluates to AttributeAssignments Section 5.39 and 5.40 of XACML 3.0 core spec: If an AttributeAssignmentExpression evaluates to an atomic attribute value, then there MUST be one resulting AttributeAssignment which MUST contain this single attribute value. If the AttributeAssignmentExpression evaluates to a bag, then there MUST be a resulting AttributeAssignment for each of the values in the bag. If the bag is empty, there shall be no AttributeAssignment from this AttributeAssignmentExpression
        Parameters:
        context - Individual Decision evaluation context
        mdpContext - the context of the Multiple Decision request that the context belongs to if the Multiple Decision Profile is used.
        Returns:
        non-null AttributeAssignments; empty if no AttributeValue resulting from evaluation of the Expression
        Throws:
        org.ow2.authzforce.core.pdp.api.IndeterminateEvaluationException - if evaluation of the Expression in this context fails (Indeterminate)
