 					<h4>Conformance Model</h4>
 					<p>There are several areas for exploration in how conformance can work. These opportunities may or may not be incorporated. They need to work together, and that interplay will be governed by the design principles</p>
 					<ul>
-						<li><strong>Measurable Guidance</strong>: Certain accessibility guidance is quite clear and measurable. Others, far less so. Some needs of people with disabilities, especially cognitive and low vision disabilities, are not well served by guidance that can only be measured by a true/false statement. If we allow multiple means of measurement, in addition to true/false statements, then we may include new accessibility guidance that benefits groups that may have been underserved in the past.</li>
-						<li><strong>Task-Based Assessment</strong>: Moving away from strictly web pages and web sites as a collection of web pages, WCAG 3.0 could set the scope of conformance as a comprehensive set of tasks defined by the author of the site or application. A properly marked up button doesn't help anybody if the user can't complete the task at hand. Task-based assessment allows flexibility for the conformance of complex applications that are not conducive to component/tag assessment or full-page assessment.</li>
-						<li><strong>Accessibility Supported</strong>: As technologies evolve, the interoperability of content, user agents, and assistive technology will continue to blur. Interoperability may be affected by any number of factors outside of the control of the author and publisher of digital content. WCAG 3.0 can include advice to user agents and assistive technology developers. Authors are not responsible for interoperability problems beyond a reasonable effort.</li>
+						<li><strong>Measurable Guidance</strong>: Certain accessibility guidance is best expressed as a true/false statement. Others far less so. There are needs of people with disabilities, especially cognitive and low vision disabilities, that are better captured by a different type of measurement. WCAG 3.0 can include multiple means of measurement, in addition to true/false statements, allowing inclusion of more accessibility guidance.</li>
+						<li><strong>Scope Options</strong>: WCAG 3.0 conformance could include web pages, web sites, page sections, individual components, and conformance based on a set of tasks as defined by the author of the site or application. A task-based assessment would allow flexibility for conformance of complex applications that go beyond component/tag assessment or full-page assessment.</li>

Interoperability may be affected by any number of factors outside of the control of the author and publisher of digital content.
