wso2 - Bitwise AND function in XACML -

using ws02 xacml evaluation engine there bitwise , function evaluate 2 values? if not there provide custom function evaluation engine? if can provide pointers on how to that?

first things first:

• in xacml, there , function. , function takes 2 boolean expressions e.g. and(isvalid, isopen) or and(role=="manager", usergroup==documentgroup). function supported in xacml implementations - work axiomatics provides xacml 3.0 engine , support it.

as custom functions:

• xacml called extensible precisely because can extend new datatypes, functions, combining algorithms, , more. can therefore implement own custom function. xacml engine use should able let load custom functions. again, do.

one group that's been defining several custom datatypes , functions geoxacml. define geographical datatypes e.g. area. can check out here.
