Twilio delivery method: why is "message" a required parameter for the Notification class?

[mikepond]

I'm confused by the requirement to require a message parameter for the Notification class in order to use the Twilio delivery method. I'm currently just sending in a generic string that I'm not even using in the actual SMS message because I'm generating the message within the notification class, just as I do with any other delivery method.

Do you have a code example? I don't know that I am following.
