+        <li><em>User Need 19:</em> Users with learning or cognitive disabilities or who use assistive technologies need to be able to learn collaboration tools efficiently, including software with which they are unfamiliar and which is necessary to the task at hand.</li>
+        <li><em>REQ 19:</em> Support the user interface conventions of the user's operating system, desktop environment, and assistive technology. For example, some assistive technologies, notably screen readers, provide commands and features for interacting with comments and revisions, which should be supported by collaboration tools to which these functions are applicable.</li>
