45 * <code>EntityReference</code> nodes may be used to represent an entity
46 * reference in the tree. Note that character references and references to
47 * predefined entities are considered to be expanded by the HTML or XML
48 * processor so that characters are represented by their Unicode equivalent
49 * rather than by an entity reference. Moreover, the XML processor may
50 * completely expand references to entities while building the
51 * <code>Document</code>, instead of providing <code>EntityReference</code>
52 * nodes. If it does provide such nodes, then for an
53 * <code>EntityReference</code> node that represents a reference to a known
54 * entity an <code>Entity</code> exists, and the subtree of the
55 * <code>EntityReference</code> node is a copy of the <code>Entity</code>
56 * node subtree. However, the latter may not be true when an entity contains
57 * an unbound namespace prefix. In such a case, because the namespace prefix
58 * resolution depends on where the entity reference is, the descendants of
59 * the <code>EntityReference</code> node may be bound to different namespace
60 * URIs. When an <code>EntityReference</code> node represents a reference to
61 * an unknown entity, the node has no children and its replacement value,
62 * when used by <code>Attr.value</code> for example, is empty.
63 * <p>As for <code>Entity</code> nodes, <code>EntityReference</code> nodes and
64 * all their descendants are readonly.
65 * <p ><b>Note:</b> <code>EntityReference</code> nodes may cause element
66 * content and attribute value normalization problems when, such as in XML
67 * 1.0 and XML Schema, the normalization is performed after entity reference
68 * are expanded.
69 * <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>.
