Some modules alter the number, names or types of their parameters. These are fully dynamic and most difficult to deal with in workflow systems.

Other modules only want to alter the "lesser" properties of their parameters, such as the items of a multiple choice. These are only "quasi-dynamic" and are easier to deal with in many circumstances.

It would be best if there were an easy way to differentiate between these two scenarios. At the moment, both types of commands extend DynamicCommand, with no way to tell the difference.
