Description

This infrequently used interface represents an entity in an
XML
document type definition (DTD). It is never used with HTML documents.

The name of the entity is specified by the
nodeName property inherited from the Node
interface. The entity content is represented by the child nodes of
the Entity node. Note that Entity nodes and their children are not
part of the document tree (and the parentNode
property of an Entity is always null). Instead, a
document may contain one or more references to an entity; see
EntityReference for more information.

Entities are defined in the DTD of a document, either as part of an
external DTD file or as part of an "internal subset" that
defines local entities specific to the current document. The
DocumentType interface has an entities property
that allows Entity nodes to be looked up by name. This is the only
way to obtain a reference to an Entity node; because they are part of
the document type, Entity nodes never appear as part of the document
itself.

Entity nodes and all of their descendants are read-only and cannot be
edited or modified in any way.
