   * Notations are how the Document Type Description (DTD) records hints
   * about the format of an XML "unparsed entity" -- in other words,
   * non-XML data bound to this document type, which some applications
   * may wish to consult when manipulating the document. A Notation
   * represents a name-value pair, with its nodeName being set to the
   * declared name of the notation.
   * <p/>
   * Notations are also used to formally declare the "targets" of
   * Processing Instructions.
   * <p/>
   * Note that the Notation's data is non-DOM information; the DOM only
   * records what and where it is.
   * <p/>
   * See the XML 1.0 spec, sections 4.7 and 2.6, for more info.
   * <p/>
   * Level 1 of the DOM does not support editing Notation contents.
