UML22 — Behavior's parameter list

We are concerned with the UML specification forcing an Behavior's parameter list to be in sync with its behavioral feature.

>From the UML 2.1.1 07-02-03, page 431 (or 445/732) it states in the 13.3.2 Behaviors section the following constraint:
[1] The parameters of the behavior must match the parameters of the implemented behavioral feature

We feel that this constraint is unnecessary. The parameter list of a Behavior element can be derived from its behavioral feature. Forcing the Behavior to have its own list of parameters has practical implementation problems such as needlessly increasing the size of the UML model, and worse, forcing one to preform the tedious task (or the tool to preform the extra overhead) of keeping the parameter lists of the Behavior and its behavioral feature in sync.

We would like to request that this constraint is removed from the specification.
