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