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