    + +

    To respond to base URL changes for a + Document document:

    + +
      +

    1. The user agent should update any user interface elements which are displaying affected + URLs, or data derived from such URLs, to the user. Examples of such user interface elements would + be a status bar that displays a hyperlink's url, or some user interface which displays the URL + specified by a q, blockquote, ins, or del + element's cite attribute.

    2. Ensure that the CSS :link/:visited/etc. pseudo-classes + are updated appropriately.
