# Interface Notation

All Superinterfaces:
  `Node`

public interface Notation extends Node
This interface represents a notation declared in the DTD. A notation either declares, by name, the format of an unparsed entity (see section 4.7 of the XML 1.0 specification [XML 1.0]), or is used for formal declaration of processing instruction targets (see section 2.6 of the XML 1.0 specification [XML 1.0]). The `nodeName` attribute inherited from `Node` is set to the declared name of the notation.

The DOM Core does not support editing `Notation` nodes; they are therefore readonly.

A `Notation` node does not have any parent.

See also the Document Object Model (DOM) Level 3 Core Specification.

Since:
  1.4, DOM Level 2
