/**
 * <P>The AccessibleHypertext class is the base class for all
 * classes that present hypertext information on the display.  This class
 * provides the standard mechanism for an assistive technology to access
 * that text via its content, attributes, and spatial location.
 * It also provides standard mechanisms for manipulating hyperlinks.
 * Applications can determine if an object supports the AccessibleHypertext
 * interface by first obtaining its AccessibleContext (see {@link Accessible})
 * and then calling the {@link AccessibleContext#getAccessibleText}
 * method of AccessibleContext.  If the return value is a class which extends
 * AccessibleHypertext, then that object supports AccessibleHypertext.
