+ /**
+ * An interface used for objects which implement linking between
+ * multiple resource or content locations, or multiple 'markers'
+ * within a single document. A Hypertext instance is associated with
+ * one or more Hyperlinks, which are associated with particular
+ * offsets within the Hypertext's included content.
+ *
+ * @note While this interface is derived from ::Text,
+ * there is no requirement that Hypertext instances have
+ * textual content; they may implement ::Image as well,
+ * and Hyperlinks need not have non-zero text offsets.
