-              The action taken when an <a>event</a>, typically initiated by users through an input device, causes an element to fulfill a defined role. The role may be defined for that element by the
-              host language, or by author-defined variables, or both. The role for any given element may be a generic action, or may be unique to that element. For example, the activation behavior of

-              the link specified in the <code>href</code> attribute, with the further optional parameter of specifying the browsing context for the traversal (such as the current window or tab, a
-              named window, or a new window); the activation behavior of an <abbr title="Hypertext Markup Language">HTML</abbr> <code>&lt;input&gt;</code> element with the <code>type</code> attribute
-              value <code>submit</code> shall be to send the values of the form elements to an author-defined <abbr title="Internationalized Resource Identifiers">IRI</abbr> by the author-defined
