---------------------------------
Proposed resolution for Issue 92:
A new subelement of the process root element is used to declare extensions
used in the process and specify whether they must be understood by the
BPEL runtime.

Rationale:
This declaration provides information needed by the process deployer in
order to decide whether a BPEL process containing language extensibility
elements can be executed by the runtime.

Add text to section 6.2. The Structure of a Business Process

   <process ...>
      ...
      <extensions>?
         <extension namespace="anyURI" mustUnderstand="yes|no"/>+
      </extensions>
      ...
   </process>

Add text to section 6.3. Language Extensibility

   The "extensions" subelement of the process is used to declare the
   namespaces of ALL BPEL extension attributes/elements and indicate
   whether they carry runtime semantics that must be understood by
   the BPEL runtime. If this criteria is not met, then the BPEL
   implementation MUST reject the process.

   If the runtime does not support one or more of the extensions with
   mustUnderstand="true", then the process MUST NOT be deployed.
   Extensions declared with mustUnderstand="false" MAY be ignored by the
   runtime.
