Question about message with a single node binding

Dear Working Group,

I have a question about what a message action should do when it has a 
single node binding which does not resolve to a node. For controls that 
situation is specified so the control will act disabled but is this 
clearly specified for message, help, hint, alert and label?

Please see the attached testcase for an example.

Best regards,
David
