The dream of WS-CDL
The dream of BPEL: an engine implements your business based upon the BPEL specification, interpreted as a program. 
Problem with BPEL: very difficult to "reuse" sections of BPEL, because they rely upon local state that might not be relevant except in the specific BPEL.
The dream of WS-CDL: define best practices for interacting with specific services, independent of the application! 
WS-CDL is not intended as an exhaustive description of a process, but rather, a more comprehensive description of "how to use" a service than its WSDL.
