+ *Purpose:* Used by a message processor to determine whether to handle incoming events or messages.
Minimum Configuration: None.
Discussion: This filter determines whether or not a message processor should process an incoming event or message. You can use the On Unaccepted property to optionally specify the name of the message processor that should handle any unaccepted events. Check the Throw On Unaccepted box to throw an exception if a message or event is not handled. The default when not checked is to not throw an exception.
A Message Filter may also include nested filters. Nested filters let you apply more complex logic to the filter. See [Logic Filter] for more details about nesting filters.
