* implements this interface and registers an instance with the SAX
* parser. The parser uses the instance to report basic
* document-related events like the start and end of elements and
* character data.
*
* The order of events in this interface is very important, and
* mirrors the order of information in the document itself. For
* example, all of an element's content (character data, processing
* instructions, and/or subelements) will appear, in order, between
* the startElement event and the corresponding endElement event.
