Do you really believe in THIS? Absolutely. Understanding the model will not require that the model itself provides the fundament of human understanding. Whenever the expression "Send a message - done!" answers a question about the functioning of a system, then indeed, done! The two teams that Simon has mentioned should be able to communicate meaningfully this way. For example, sometimes it is "understood" (borrowing math speak) what sending a message means, given some architecture. If more detail is needed, it is up to the model makers and programmers to agree on a useful rule regarding specification en detail.
