     31 * The AtkHyperlinkImpl interface should be supported by objects
     32 * exposed within the hierarchy as children of an AtkHypertext container
     33 * which correspond to "links" or embedded content within the text.
     34 * HTML anchors are not, for instance, normally exposed this way,
     35 * but embedded images and components which appear inline in the
     36 * content of a text object are. The AtkHyperlinkIface interface
     37 * allows a means of determining which children are hyperlinks in this
     38 * sense of the word, and for obtaining their corresponding AtkHyperlink 
     39 * object, from which the embedding range, URI, etc. can be obtained.
     40 *
     41 * To some extent this interface exists because, for historical 
     42 * reasons, AtkHyperlink was defined as an object type, not an interface.
     43 * Thus, in order to interact with AtkObjects via AtkHyperlink semantics,
     44 * a new interface was required.
