Create an instance of a framer message on which per-
message options can be configured when sending data
on a connection. This is intended to be used by the
application above the connection to send message data
down to the framer protocol instance.
Create a message using a framer instance rather than
the definition. This can be used to deliver messages
from a framer implementation to the application.
