/**
* This interface represents a known entity, either parsed or unparsed, in an
* XML document. Note that this models the entity itself <em>not</em> the entity declaration.
* <p>The <code>nodeName</code> attribute that is inherited from
* <code>Node</code> contains the name of the entity.
* <p>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
* <code>EntityReference</code> nodes in the document tree.
* <p>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 <a href='http://www.w3.org/TR/2004/REC-xml-20040204#intern-replacement'>
* replacement text</a> is available, the corresponding <code>Entity</code> node's child list
* represents the structure of that replacement value. Otherwise, the child
* list is empty.
* <p>DOM Level 3 does not support editing <code>Entity</code> nodes; if a
* user wants to make changes to the contents of an <code>Entity</code>,
* every related <code>EntityReference</code> node has to be replaced in the
* structure model by a clone of the <code>Entity</code>'s contents, and
* then the desired changes must be made to each of those clones instead.
* <code>Entity</code> nodes and all their descendants are readonly.
* <p>An <code>Entity</code> node does not have any parent.
* <p ><b>Note:</b> If the entity contains an unbound namespace prefix, the
* <code>namespaceURI</code> of the corresponding node in the
* <code>Entity</code> node subtree is <code>null</code>. The same is true
* for <code>EntityReference</code> nodes that refer to this entity, when
* they are created using the <code>createEntityReference</code> method of
* the <code>Document</code> interface.
* <p>See also the <a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-Core-20040407'>Document Object Model (DOM) Level 3 Core Specification</a>.
