Need more examples in the specification

This is feedback from our development team:

The specification needs a lot more examples to help the reader 
understand the concepts. The specification requires understanding of 
both the BPEL technology and SCA technology. This, at this point, is not 
something that is common. Readers are familiar with BPEL or SCA, in most 
cases, and provide plenty of examples would help newcomers grok the 
specification.
