 ### Added
 - Extension mechanism to switch HashMap/HashSet implementation; default implementation is based on native JRE and Guava.
 - Validation of 'n' argument (minimum of *true* arguments) of XACML 'n-of' function if this is constant (must be a positive integer not greater than the number of remaining arguments)

-- Behavior of "unordered" rule combining algorithms (deny-overrides, permit-overrides, deny-unless-permit and permit-unless deny), i.e. for which the order of evaluation may be different from the order of declaration: child elements are re-ordered for more efficiency (e.g. Deny rules evaluated first in case of deny-overrides algorithm), therefore the algorithm implementation, the order of evaluation in particular, now differs from ordered-* variants.

 ### Removed
 - Dependency on Koloboke, replaced by extension mechanism mentioned in *Added* section that would allow to switch from the default HashMap/HashSet implementation to Koloboke-based.
