The abstract says "The TC will develop a data model and XML vocabulary to exchange prices and product definitions for transactive energy markets." But price takers and others need price and product definition exchange. The text is too narrow.
The text "It is not in scope for this TC to define specifications for markets, nor how prices are determined, nor the mechanisms for interoperation. The TC will coordinate with others to ensure that commonly used market and communication models are supported." should be rewritten, as it anticipates rather than describes the document in hand.
