In a selection transition, a coupling can be omitted by a jump transition or end transition.
In a selective transition, the number of branches and the number of couplings may be different. However, a
selection branch and parallel coupling or a parallel branch and selection coupling cannot be combined.
When transition condition "b" is satisfied at the step "n" operation output, processing will proceed in
order through steps "n+1", "n+2" and "n+3". When transition condition "d" is satisfied, processing will
jump to step "n". ( Page 67 Jump transition)
