/**
* This interface represents a known entity, either parsed or unparsed, in an
* XML document. Note that this models the entity itself not the entity declaration.
* The nodeName attribute that is inherited from
* Node contains the name of the entity.
*
An XML processor may choose to completely expand entities before the
* structure model is passed to the DOM; in this case there will be no
* EntityReference nodes in the document tree.
*
XML does not mandate that a non-validating XML processor read and
* process entity declarations made in the external subset or declared in
* parameter entities. This means that parsed entities declared in the
* external subset need not be expanded by some classes of applications, and
* that the replacement text of the entity may not be available. When the
* replacement text is available, the corresponding Entity node's child list
* represents the structure of that replacement value. Otherwise, the child
* list is empty.
*
DOM Level 3 does not support editing Entity nodes; if a
* user wants to make changes to the contents of an Entity,
* every related EntityReference node has to be replaced in the
* structure model by a clone of the Entity's contents, and
* then the desired changes must be made to each of those clones instead.
* Entity nodes and all their descendants are readonly.
*
An Entity node does not have any parent.
*
Note: If the entity contains an unbound namespace prefix, the
* namespaceURI of the corresponding node in the
* Entity node subtree is null. The same is true
* for EntityReference nodes that refer to this entity, when
* they are created using the createEntityReference method of
* the Document interface.
*
See also the Document Object Model (DOM) Level 3 Core Specification.
