For ActivityParameterNode, you therefore DO NOT have to use the workaround described here:

MagicDraw/Cameo 19SP3: Continuous and Discrete have metaclass [ActivityEdge, ObjectNode, Parameter] not just [ActivityEdge, Parameter] (via Rate), so may be applied directly to Pin and ActivityParameterNode

[SysML-1.6] SysML provides extensions that might be very loosely grouped under the term “continuous,” but are generally applicable to any sort of distributed flow of information and physical items through a system.

[SysML-1.6] Discrete and continuous flows are unified under rate of flow, as is traditionally done in mathematical models of continuous change, where the discrete increment of time approaches zero.

[SysML-1.6] Continuous rate is a special case of rate of flow (see Rate) where the increment of time between items approaches zero. It is intended to represent continuous flows that may correspond to water flowing through a pipe, a time continuous signal, or ...

[SysML-1.6] Rate ... When the stereotype is applied to a parameter, the parameter shall be streaming, and the stereotype gives the number of objects or values that flow in or out of the parameter per time interval while the behavior or operation is executing.
