The introduction (section 3) should use bullets or a numbered list for the three schemas starting on line 307.
Somewhere in this section there should be a table or list that indicates the following (update namespaces per other issues):
- emix.xsd has target namespace http://docs.oasis-open.org/ns/emix and consistes of three files - emix.xsd, emix-requirements.xsd, and emix-warrants.xsd
- Power.xsd has target namespace http://docs.oasis-open.org/ns/emix/power consists of three files - power.xsd, power-product.xsd, and power-quality.xsd.
*Resource.xsd has target namespace http://docs.oasis-open.org/ns/emix/power and consists of one file - resource.xsd
A figure may be useful as well to show the grouping.
