Subject: Re: [wsbpel] New Issue - Import in AP: basic executable completion

Title: [wsbpel] New Issue - Import in AP: basic executable completion
what about <extensions>?

and a side question:  what are the completion rules for things outside of the primary activity and handlers?  for instance, can I add a <variables> element if there isn't one?  If not, can I put an <opaque> there instead?  Can I add a <variable> element to an existing <variables> element?  Partnerlinks?  CorrelationSets?  etc.?

The AP basic completion rules were defined before BPEL mandatory
<import>s were introduced. The question that is open now is how do they
affect the basic executable completion rule that is used to
syntactically validate an Abstract Process (from any profile).

Currently,  the basic exec completion is :

A Basic Executable Completion of an Abstract Process is defined as an
Executable Completion whose allowed syntactic transformations are
limited to Opaque Token Replacement, plus the addition of an activity
with createInstance="yes" if none are present in the Abstract Process
(per clause [5] of section 13.1.3. Hiding Syntactic Elements).

Where  1b1 is:

•       Opaque Token Replacement: Replacing every opaque token (including
those omitted using the omission-shortcut) with a corresponding
Executable token. For example, replacing an opaque activity with an

So, without changing anything and taking the usage of <import> means
that one cannot (1) use wsdl/xsd/etc artifacts in the AP that have not
been defined in an imported documents and (2) replace opaque tokens with
artifacts not defined in these documents for the basic exec completion.

The question is do we want to allow (1) and (2), or just (2), or niether?

This affects section 13.1 and the two profiles (they have to decide
whether their completions allow adding arbitrary imports, aside from the
basic exec profile )
