## 4.3. Benefits and Considerations

Benefits:

- Allows for loosely typed, and loosely coupled systems. Transport and Application are separate

- Changes to the data sent in the payload do not necessarily change the WSDL. Meaning the web service does not change because the schema changed.

Considerations:

- All transport traffic is going through one end point. This could potentially have scalability issues depending on the amount of data that is coming into the system.

- Implementers will need to implement routing and extraction code in order to determine what to do with the payload received.

- Need to implement logic in order to handle contents that are not understood.

- Need to negotiate out of band using other services to describe what payloads are understood and handled by a particular trading partner.
