Jamie,

The intent of the PARAMETER_DESCRIPTION message was for it to only be used to describe very basic GET/SET parameters for a single function as these are very common and easy to understand. Every manufacturer tends to have those menu settings that are specific to their product, so this was an attempt at addressing that.

As a consequence of that this message was intended to be used where there are no other modifiers in the GET request or the SET response message that would need to be specified. For the situation you describe where you want to get/set curves for individual dimmer channels then it would make the most sense for the dimmers to be implemented as sub-devices. The sub-device number would then be used to specify which "channel" rather than putting it in the PD area as well.

Hope this helps clarify.
