The Access Element
Current Definition of the access Element
The access element assigns an accessibility mapping to elements within a document. Actuating the mapping results in the element gaining focus (either the document focus or an inspection focus, as determined by the user agent), and, if set by the author and permitted by the user's settings, in one or more other events being activated.
An access element must have either a targetrole or a targetid attribute specified. If neither a targetrole nor a targetid attribute are specified, the user agent MUST NOT define a mapping nor deliver any events.
