AuthzForce PDP extensions for JSON value processing, in particular JSONPath evaluation; it provides the XACML datatype 'urn:ow2:authzforce:feature:pdp:datatype:json' for JSON object/array values, and XACML functions that evaluate a JSON path (second parameter of standard string datatype) against an input JSON object/array (first parameter of datatype 'urn:ow2:authzforce:feature:pdp:datatype:json') and return the result of this evaluation. The return datatype depends on the actual function used: 'urn:ow2:authzforce:feature:pdp:function:string-from-json-path' returns a bag of strings, 'urn:ow2:authzforce:feature:pdp:function:integer-from-json-path' returns a bag of integers, 'urn:ow2:authzforce:feature:pdp:function:double-from-json-path' returns a bag of doubles, 'urn:ow2:authzforce:feature:pdp:function:boolean-from-json-path' returns a bag of booleans.
