How to Return True or False from a Policy

You cannot specify a return type for a policy directly. However, you can pass one of the following types of facts to the policy, have the policy change the value of the fact to true or false, and then check the value of the property/element/column after the policy is executed:

• A .NET object with a property of type Boolean

• An XML document with an element of type Boolean

• A database table with a column of type Boolean
