As a part of the OMG business process metamodel submitters group I can
report one item that has NO controversy - processes have parts and these
parts change over time.    (01)

My comment here, is concerning processes.  I can envision a 4D object
(process) having component parts (sub-processes?).  In that case, should we
not also concerning indexing x part_of y (where y is a process) also by
time?  The alternative seems to suggest that all processes (and
sub-processes) are without time boundary.    (05)
