Dynamic ports are opt-in, and a node that does not opt in has none
Dynamic ports let an author add connection points to one node instance beyond what its processor declares. Nothing gets them by accident: a node type has to ask for them, and the definitions start empty.
The rule
Normative: this is the rule
- A node type opts a node in to dynamic ports.
- The opt-in declares two reserved parameters, one holding the node's dynamic input port definitions and one its dynamic output port definitions, each a list whose default is empty.
- A node that has not opted in has no dynamic ports.
