4.7 XML Comments

XML comments are notes for humans, not programs:
The LexicalHandler interface introduces the method
- comment(char[] ch, int start, int length)
for handling comment events.
The interface XMLReader introducess the method
- setProperty(String name, Object handler)
for registering non-core handlers with a XML reader.
The property id
- http://xml.org/sax/properties/lexical-handler
should be used for implementations of LexicalHandler.
An implementation of LexicalHandler should also hndle the methods startEntity(String), endEntity(String), startCDATA(), endCDATA(), startDTD(String, String, String), and endDTD().

xmlReader.setProperty(
"http://xml.org/sax/properties/lexical-handler",
new MyLexicalHandler()
);
