Section 14:
Line 740 - are warrants only for "power" Surely they address "energy" as well. Reword sentence.
Paragraph starting 740: This implies that there may be multiple schedules, one for warrants, one for other things. Is that intended? (I think it's true, but "Warrants start as Product Descriptions..." seems a bit informal. "Warrants are an extension of Product Descriptions..." is better.
Line 745: "Warrants MAY be applicable only in certain jurisdictions." ...
Line 746 - change year to 2011.
Lines 746-747 - capitalization on Hydro Power/Hydro power is not consistent. Make both words lower case. Change "markers" to "markets"
Lines 750-751 Second sentence is repetitive. Reword: "For example, consider a product where its source of energy has an Environmental Warrant indicating that a particular authority certifies it as renewable. That certificate can be separately traded, so the Warrant should specify if the certificate is (1) accompanying the energy, ..."
Is that the case? We don't define warrants other than an extendable type. This is going into the "should/could" realm and straying from what's in the specification.
Perhaps better to replace the discussions starting with (altered) "That certificate..." with "The detailed specification of warrants is not part of version 1.0 of this specification."
