We raised issue DER-107 to add a note to this effect with some additional comments (see the issue itself for those).
At the top level related to DER-84, there is currently no connection between a commodity instrument and a negotiable commodity or price of a commodity or index. We need to construct the union of those things and move the restriction on commodity spot instrument up to the commodity instrument level (or retain it but have the higher level / broader restriction be on the instrument). For a given negotiable commodity there needs to be the notion of what quantity of that commodity the instrument is talking about. The price would be expressed in an offer, but the contract would specify how much of some commodity if it is about the physical commodity, or price of a physical commodity or price movement of a physical commodity. Indexes are treated differently so we should ensure that we can handle that as well. We decided to push further discussion on this topic to next week.
