<DL>
<DD>Receive an object for locating the origin of SAX document events.

 <p>SAX parsers are strongly encouraged (though not absolutely
 required) to supply a locator: if it does so, it must supply
 the locator to the application by invoking this method before
 invoking any of the other methods in the ContentHandler
 interface.</p>

 <p>The locator allows the application to determine the end
 position of any document-related event, even if the parser is
 not reporting an error.  Typically, the application will
 use this information for reporting its own errors (such as
 character content that does not match an application's
 business rules).  The information returned by the locator
 is probably not sufficient for use with a search engine.</p>

 <p>Note that the locator will return correct information only
 during the invocation of the events in this interface.  The
 application should not attempt to use it at any other time.</p><DD><DL>

 <p>The SAX parser will invoke this method only once, and it will

<DL>
<DD>Begin the scope of a prefix-URI Namespace mapping.

 <p>The information from this event is not necessary for
 normal Namespace processing: the SAX XML reader will 
 automatically replace prefixes for element and attribute
 names when the <code>http://xml.org/sax/features/namespaces</code>
 feature is <var>true</var> (the default).</p>

 <p>There are cases, however, when applications need to
 use prefixes in character data or in attribute values,
 where they cannot safely be expanded automatically; the
 start/endPrefixMapping event supplies the information
 to the application to expand prefixes in those contexts
 itself, if necessary.</p>

 <p>Note that start/endPrefixMapping events are not
 guaranteed to be properly nested relative to each-other:
 all startPrefixMapping events will occur before the
 corresponding <A HREF="../../../org/xml/sax/ContentHandler.html#startElement(java.lang.String, java.lang.String, java.lang.String, org.xml.sax.Attributes)"><CODE>startElement</CODE></A> event, 
 and all <A HREF="../../../org/xml/sax/ContentHandler.html#endPrefixMapping(java.lang.String)"><CODE>endPrefixMapping</CODE></A>
 events will occur after the corresponding <A HREF="../../../org/xml/sax/ContentHandler.html#endElement(java.lang.String, java.lang.String, java.lang.String)"><CODE>endElement</CODE></A> event, but their order is not otherwise 
 guaranteed.</p>

 <p>There should never be start/endPrefixMapping events for the
 "xml" prefix, since it is predeclared and immutable.</p><DD><DL>

<DL>
<DD>Receive notification of the beginning of an element.

 <p>The Parser will invoke this method at the beginning of every
 element in the XML document; there will be a corresponding
 <A HREF="../../../org/xml/sax/ContentHandler.html#endElement(java.lang.String, java.lang.String, java.lang.String)"><CODE>endElement</CODE></A> event for every startElement event
 (even when the element is empty). All of the element's content will be
 reported, in order, before the corresponding endElement
 event.</p>

 <p>This event allows up to three name components for each
 element:</p>

 <ol>
 <li>the Namespace URI;</li>
 <li>the local name; and</li>
 <li>the qualified (prefixed) name.</li>
 </ol>

 <p>Any or all of these may be provided, depending on the
 values of the <var>http://xml.org/sax/features/namespaces</var>
 and the <var>http://xml.org/sax/features/namespace-prefixes</var>
 properties:</p>

 <ul>
 <li>the Namespace URI and local name are required when 
 the namespaces property is <var>true</var> (the default), and are
 optional when the namespaces property is <var>false</var> (if one is
 specified, both must be);</li>
 <li>the qualified name is required when the namespace-prefixes property
 is <var>true</var>, and is optional when the namespace-prefixes property
 is <var>false</var> (the default).</li>
 </ul>
