I can't help you with the code referance. I do have a solution.
Lutron has special Rec and cord caps for dimming use. The cord cap is slightly different but will work in any outlet. The dimming rec has a smaller size terminal and a rejection bump. No other cord cap fit it.
Call for prices first. List price seems high. They claim to be the only maker of such a thing.

Active one I just inspected a home with this Lutron dimming receptacle device installed. While it is a Listed device it doesn't satisfy the requirement for receptacles in the wall space. I gave the contractor an option of changing to a "standard" receptacle or adding a "standard" receptacle. He added a standard receptacle.

OK, so it's not that I can't dim a receptacle, just that the dimmer must be rated or listed for that purpose. What I actually want to do is dim cabinet lights that have a X-FMR mounted above a cabinet, so the recep isn't a convenience recep in the first place. The lutron recep sounds like a good idea anyway.

An interesting thing about that Lutron recept is that, while it has a ground contact, it doesn't appear that there exist any plugs with a ground pin that will actually mate with the recept--their plugs are two-pronged. Unless I missed one somewhere.

There have been issues applying dimmers to general use receptacles since you cannot predict what will be plugged into it later on. Some appliances react very poorly to receiving a solid state dimmer output!! Likewise, the system you are trying to connect MUST be rated for connection to a dimmer and may specify the correct device(s) to use. Certain dimmers are NOT rated to operate magnetic devices such as transformers. Be careful!!
