A parameter set is always used in combination with other parameter sets that
mutually exclude each other. They each contain all input or output parameters

inputs or produces alternative outputs. Two parameter sets may have common
parameters, but they must not be fully identical.
The pins that belong to a parameter set are enclosed by an additional rectangle
