 						<p><strong>Guidelines</strong> - Under the principles are guidelines. The 13 guidelines provide the basic goals that authors should work toward in order to make content more accessible to users with different disabilities. The guidelines are not testable, but provide the framework and overall objectives to help authors understand the success criteria and better implement the techniques.</p>

 					<li>
-						<p><strong>success criteria</strong> - For each guideline, testable success criteria are provided to allow WCAG 2.2 to be used where requirements and conformance testing are necessary such as in design specification, purchasing, regulation, and contractual agreements. In order to meet the needs of different groups and different situations, three levels of conformance are defined: A (lowest), AA, and AAA (highest). Additional information on WCAG levels can be found in <a href="https://www.w3.org/WAI/WCAG22/Understanding/conformance#levels">Understanding Levels of Conformance</a>.</p>

 						<p><strong>Sufficient and Advisory Techniques</strong> - For each of the <em>guidelines</em> and <em>success criteria</em> in the WCAG 2.2 document itself, the working group has also documented a wide variety of <em>techniques</em>. The techniques are informative and fall into two categories: those that are <em>sufficient</em> for meeting the success criteria and those that are <em>advisory</em>. The advisory techniques go beyond what is required by the individual success criteria and allow authors to better address the guidelines. Some advisory techniques address accessibility barriers that are not covered by the testable success criteria. Where common failures are known, these are also documented.
