Hi all,

also with this one, please feel free to forward ;)

Two things here:

-For point 1: there are actually three as per the doc. Also note that the
following is also allowed (the doc allows for these as it is)
   c)AbsProc--to-->Exec artifact(s) which does not have to be BPEL.
   d)AbsProc--to-->AbsProc (refinement, where the second adds some but
not all necessary detail to the first.

-For point 2, agreed.

-For point 3, see my other mail.


----
 From Nick:

Some things of interest to add for clarity:
-One of the points, was in a thread with Rania, myself and Satish:
There are only two patterns:
     a) ExecProc--to-->AbsProc
     b) AbsProc--to-->ExecProc
-Another point was that opq-activities (one type of the opaque
placeholder feature) are useful for all the patterns
and should not be focused just on templates. An example that was given
was using opq-activities for resolving Issue99.
-Rania provided an excellent analysis of the continuum of opaque
placeholders for all the patterns (I guess Rania you can
work as a consultant in NYC ;->) that is maybe of interest to all of us.
Since it is kind of difficult to replicate all the arguments here it may
be useful to forward the
relevant discussion threads to the list as context. What do you guys think?
