/**
 * A representation of an XML name.  This interface provides methods for
 * getting the local and namespace-qualified names and also for getting the
 * prefix associated with the namespace for the name. It is also possible
 * to get the URI of the namespace.
 * <P>
 * The following is an example of a namespace declaration in an element.
 * <PRE>
 *   &lt;wombat:GetLastTradePrice xmlns:wombat="http://www.wombat.org/trader"&gt;
 * </PRE>
 * ("xmlns" stands for "XML namespace".)
 * The following
 * shows what the methods in the <code>Name</code> interface will return.
 * <UL>
 *  <LI><code>getQualifiedName</code> will return "prefix:LocalName" =
 *      "WOMBAT:GetLastTradePrice"
 *  <LI><code>getURI</code> will return "http://www.wombat.org/trader"
 *  <LI><code>getLocalName</code> will return "GetLastTracePrice"
 *  <LI><code>getPrefix</code> will return "WOMBAT"
 * </UL>
 * <P>
 * XML namespaces are used to disambiguate SOAP identifiers from
 * application-specific identifiers.
 * <P>
 * <code>Name</code> objects are created using the method
 * <code>SOAPEnvelope.createName</code>, which has two versions.
 * One method creates <code>Name</code> objects with
 * a local name, a namespace prefix, and a namespace URI.
 *  and the second creates <code>Name</code> objects with just a local name.
 * The following line of
 * code, in which <i>se</i> is a <code>SOAPEnvelope</code> object, creates a new
 * <code>Name</code> object with all three.
 * <PRE>
 *     Name name = se.createName("GetLastTradePrice", "WOMBAT",
 *                                "http://www.wombat.org/trader");
 * </PRE>
 * The following line of code gives an example of how a <code>Name</code> object
 * can be used. The variable <i>element</i> is a <code>SOAPElement</code> object.
 * This code creates a new <code>SOAPElement</code> object with the given name and
 * adds it to <i>element</i>.
 * <PRE>
 *     element.addChildElement(name);
 * </PRE>
 * <P>
 * The <code>Name</code> interface may be deprecated in a future release of SAAJ
 * in favor of <code>javax.xml.namespace.QName<code>
 * @see SOAPEnvelope#createName(String, String, String) SOAPEnvelope.createName
 * @see SOAPFactory#createName(String, String, String) SOAPFactory.createName
