Node EntityReference

Description

This infrequently used interface represents a reference from an XML
document to an entity defined in the document's DTD. Character
entities and predefined entities such as <
are always expanded in XML and HTML documents, and EntityReference
nodes never appear in HTML documents, so programmers working
exclusively with HTML documents never need to use this interface.
Note also that some XML parsers expand all entity references.
Documents created by such parsers do not contain EntityReference
nodes.

This interface defines no properties or methods of its own. The
inherited nodeName property specifies the name of
the referenced entity. The entities property of
the DocumentType interface provides a way to look up the Entity
object with that name. Note, however, that the DocumentType may not
contain an Entity node with the specified name (because, for example,
nonvalidating XML parsers are not required to parse the
"external subset" of the DTD). In this case, the
EntityReference has no children. On the other hand, if the
DocumentType does contain an Entity node with the specified name, the
child nodes of the EntityReference are copies of the child nodes of
the Entity node and represent the content of the entity. Like Entity
nodes, EntityReference nodes and their descendants are read-only and
cannot be edited or modified.
