Concerned with the proposal to reliance of WS calendar to the formulations being developed. While there may be opportunities to leverage the use of WS calendar to some of the areas being looked at it may create considerable challenges in the others.

The consistent use of cross-cutting schedule communication (see NIST PAP04) is critical to the success of these standards, and integration across the entire smart grid including but not limited to consumption, generation, and markets. This specification would have to re-invent schedule communication, which is already coordinated across WS-Calendar, EMIX (which normatively references WS-Calendar) and Energy Interoperation (which normatively references both WS-Calendar and EMIX). Rewrite and review the ws-calendar narrative for clarity and precision, including Stop sentence after "inherited" and add discussion of inheritance earlier in document. Use WS-Calendar Gluon in first reference in each section. Add conformance section on inheritance to last section. Terminology needs to be consistent; e.g., a Gluon acts as a handle to a Sequence Capitalize Interval, Gluon, Sequence throughout as defined terms.
