<?xml version="1.0" encoding="UTF-8"?>
<interface name="Entity" inherits="Node" id="ID-527DCFF2">
<descr><p>This interface represents an entity, either parsed or
unparsed, in an XML document. Note that this models the entity
itself <emph>not</emph> the entity declaration. <code>Entity</code>
declaration modeling has been left for a later Level of the DOM
specification.</p>
<p>The <code>nodeName</code> attribute that is inherited from
<code>Node</code> contains the name of the entity.</p>
<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>
<p>XML does not mandate that a non-validating XML processor read
and process entity declarations made in the external subset or
declared in external 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 value of the entity may not be available. When the
replacement value is available, the corresponding
<code>Entity</code> node's child list represents the structure of
that replacement text. Otherwise, the child list is empty.</p>
<p>The DOM Level 2 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
<termref def="dt-descendant">descendants</termref> are <termref def="dt-readonly-node">readonly</termref>.</p>
<p>An <code>Entity</code> node does not have any parent.</p>
<note><p>If the entity contains an unbound <termref
def='dt-namespaceprefix'>namespace prefix</termref>, 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. The DOM Level 2 does not
support any mechanism to resolve namespace prefixes.</p></note>
