Lexical Events
Lexical events have to do with the way that a document was writtenand not with its content
Examples:
A comment is a lexical event () The use of an entity is a lexical event (>)
These can be dealt with by implementing the LexicalHandler interface,and set on a parser by
reader.setProperty("http://xml.org/sax/properties/ lexical-handler", mylexicalhandler);
