Remarks
Rules of this type are triggered when a new value is assigned to one of the roles of a domain relationship.
A RuleOnAttribute attribute placed on the class indicates what type of object the Rule works on and when the rule should fire (inline, local transaction commit, or top level transaction commit).
For more information and examples, see Rules Propagate Changes Within the Model.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
