Subject: Are WSDL descriptions always required for abstract processes

Title: Message
Dear
Colleagues,
I would like to see
if there is a simple and agreed answer to this question or whether I should
raise as an issue (or add in to an existing issue such as 82 or
97).
My question
is:
Are WSDL
descriptions *always* required for abstract processes. Is the answer clear
and correct in the specification?
Imagine
an process (A) that communicates with three remote processes (B), (C),
(D). Is it possible to produce an abstract process BPEL description on its
own (one XML document) that conforms to the schema and to the letter and spirit
of the textual specification, or is it required to always produce WSDL
descriptions as well - if so how many and for what? Three one for each of
the 'A' ends of the A-B, A-C and A-D relationships, three one for each of the
'B', 'C' and 'D' ends of the A-B, A-C and A-D relationships respectively,
or all of these making six in total?
The spirit of
section 15.1 (and especially the second paragraph) might be taken to suggest
that the WSDL descriptions are not required.
However, as Ugo has
pointed out to me, the portType attribute is a qualified name type and is a
required attribute on invoke, receive and reply, which implies that
mechanistically the WDSL descriptions are required at
present.
What say you
Senators?
Best
Regards,
Tony
