It is invalid to construct an ActionMessageFilter with no actions.

This type is serializable as a DataContractAttribute.

The following example creates two ActionMessageFilters, gets the action string out of one of the filters using the Actions property, tests a message against the action filters directly, and displays the result of applying the filter.
