Synchronization Issue in OWL-S with SplitJoin CC

Hi,
As discussed in many articles and talks that OWL-S
Process Model is an orchestration language like
BPEL4WS. Like BPEL4WS process model, OWL-S
ProcessModel can be used  to define composition
between different services and defining control flow
between different services (process components) within
a composition by using Control Constructs e.g.
Sequence, IfThenElse etc.

Concurrent execution of process components with in an
OWL-S composite process can be defined by using OWL-S
“Split� Control Construct and in BPEL
“Flow�
activity can be used to do same job.

Synchronization between process components with in an
OWL-S Composite process can be defined by using
“SplitJoin� Control Construct while in BPEL
we can
use “Links� with in a “Flow�
activity to
define synchronization between activities.

Now comes my Question:

I have read OWL-S specification in detail but i was
not able to find how we can use "SplitJoin" control
construct to create synchronization between process
components as we use "Links" in BPEL for
synchronization between activities. According to my
point of view there are no much specification and
details about "SplitJoin" Control Construct and about
level of synchronization and ways to create
synchronization between process components, in OWL-S
specifications.

If some one has any idea or good understanding on this
issues i will be thankfull for help in this regard.

Thanks in advance and Bye.
