Remarks
Begin the scope of a prefix-URI Namespace mapping.
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 <var>true</var> (the default).
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.
Note that start/endPrefixMapping events are not guaranteed to be properly nested relative to each other: all startPrefixMapping events will occur immediately before the corresponding #startElement startElement event, and all #endPrefixMapping endPrefixMapping events will occur immediately after the corresponding #endElement endElement event, but their order is not otherwise guaranteed.
There should never be start/endPrefixMapping events for the "xml" prefix, since it is predeclared and immutable.
