Using Internal Schemas

Before beginning on your orchestration its probably a good idea to look at these tips from Microsoft. The best i like among them is the usage of internal schemas. Not that i dont like direct message box binding as a good choice; but still. When dealing with constant change and to keep the idea of “loose coupling” in mind ; the idea of creating a set of internal schemas makes you breeze through any schema  (or namespace) changes with ease. Also addition of extra fields in schemas never broke any maps completely.
