Inclusive OR gateway is not supported in converging mode

the behavior of inclusive OR converging gateway according to bpm specification is as follows

lets assume a process

branch1
/ \

OR (diverging) - branch 2 - OR (converging)

\ /

branch 3

now any of branches may be triggered, OR converging has to
wait for all branches that were actually triggered (say
branch1 and branch 3).
we don't know to continue to wait for branch 2 or not

this is different than Exclusive OR converging or AND converging
