  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.
