Line 248 - Not clear, is the 15 minute lead time part of the product? Then disagree, these are resource properties see CIM and IRC submitted work.

For example, a resource representing a responsive load may state that 15 minutes lead time is required between notification and load reduction. This characteristic may hold true whether the response requested is for a run-time of 10 minutes or for 10 hours. EMIX specifies invariant characteristics as part of a product or resource, while offering the variable run-time to the market.
