Node
readonly String publicId
The public identifier of the notation, or null if none is specified.
readonly String systemId
The system identifier of the notation, or null if none is specified.
This infrequently used interface represents a notation declaration in the document type definition (DTD) of an XML document. In XML, notations are used to specify the format of an unparsed entity or to formally declare a processing instruction target.
The name of the notation is specified by the inherited nodeName property. Because notations appear in the DTD and not the document itself, Notation nodes are never part of the document tree, and the parentNode property is always null. The notations property of the DocumentType interface provides a way to look up Notation objects by notation name.
Notation objects are read-only and cannot be modified in any way.
