/**
 * 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} interface will return.
 * <UL>
 * <LI>{@code getQualifiedName} will return "prefix:LocalName" =
 *     "WOMBAT:GetLastTradePrice"
 * <LI>{@code getURI} will return "http://www.wombat.org/trader"
 * <LI>{@code getLocalName} will return "GetLastTracePrice"
 * <LI>{@code getPrefix} will return "WOMBAT"
 * </UL>
 * <P>
 * XML namespaces are used to disambiguate SOAP identifiers from
 * application-specific identifiers.
 * <P>
 * {@code Name} objects are created using the method
 * {@code SOAPEnvelope.createName}, which has two versions.
 * One method creates {@code Name} objects with
 * a local name, a namespace prefix, and a namespace URI.
 * and the second creates {@code Name} objects with just a local name.
 * The following line of
 * code, in which <i>se</i> is a {@code SOAPEnvelope} object, creates a new
 * {@code Name} 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} object
 * can be used. The variable <i>element</i> is a {@code SOAPElement} object.
 * This code creates a new {@code SOAPElement} object with the given name and
 * adds it to <i>element</i>.
 * <PRE>
 *    element.addChildElement(name);
 * </PRE>
