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>. 70 */ 71 public interface EntityReference extends Node { 72 } 73
