You should consider the elements you manage in the BPEL process as 
*basic services*. Following this point of view, a BPEL process should 
only interact with exposed services and it was, as far as i know, 
designed to work that way. BPEL orchestrates (tells everyone what to do 
and when to do it, even integrating human tasks into the process) and 
its XML speech means that it talks to services through XML messages.

Hope I make myself clear while trying to be helpful.
