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