/**
 * Receive notification of the logical content of a document.
 *
 * This is the main interface that most SAX applications implement: if
 * the application needs to be informed of basic parsing events, it
 * 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.
