<p>Called by the parser to give the application a locator for locating
the origin of document events.</p>
<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 DocumentHandler 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>

<p>Begin the scope of a prefix-URI Namespace mapping.</p>
<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
http://xml.org/sax/features/namespaces feature is true (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 startElement event, and all
endPrefixMapping events will occur after the corresponding endElement
event, but their order is not guaranteed.</p>
