Higher Grade Cyberlimbs and "Accessories" Options

[ClemulusRex]

While the rules clearly state that any piece of 'ware that's of a higher than Standard grade needs to have all of it's accessories purchased at the same grade, I'm still a little fuzzy on what counts as an "accessory" for cyberlimbs.

For instance, in the case of an Alphaware limb, would attribute enhancements and/or customization be considered accessories that would need to be purchased at the higher grade? I'm thinking most likely "yes", but the fact that "accessories" is a different chart from "enhancements" gives me pause. That and I'm generally in favor of anything that gives cyberlimbs a little extra boost/break.

What about largely cosmetic stuff, like casemods? Or anything else that might not normally take up Capacity?
