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