@extends java.lang.Object

 <p><code>QName</code> represents a <strong>qualified name</strong>
 as defined in the XML specifications: <a
 href="http://www.w3.org/TR/xmlschema-2/#QName">XML Schema Part2:
 Datatypes specification</a>, <a
 href="http://www.w3.org/TR/REC-xml-names/#ns-qualnames">Namespaces
 in XML</a>, <a
 href="http://www.w3.org/XML/xml-names-19990114-errata">Namespaces
 in XML Errata</a>.</p>

 <p>The value of a <code>QName</code> contains a <strong>Namespace
 URI</strong>, <strong>local part</strong> and
 <strong>prefix</strong>.</p>

 <p>The prefix is included in <code>QName</code> to retain lexical
 information <strong><em>when present</em></strong> in an {@link javax.xml.transform.Source XML input source}. The prefix is
 <strong><em>NOT</em></strong> used in {@link #equals(Object)
 javax.xml.namespace.QName.equals(Object)} or to compute the {@link #hashCode()
 javax.xml.namespace.QName.hashCode()}.  Equality and the hash code are defined using
 <strong><em>only</em></strong> the Namespace URI and local part.</p>

 <p>If not specified, the Namespace URI is set to {@link javax.xml.XMLConstants#NULL_NS_URI XMLConstants.NULL_NS_URI}.
 If not specified, the prefix is set to {@link javax.xml.XMLConstants#DEFAULT_NS_PREFIX
 XMLConstants.DEFAULT_NS_PREFIX}.</p>

 <p><code>QName</code> is immutable.</p>
