+ * 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.
