ModSAX: Proposed Core Handlers

[David Megginson]

My current proposal for the ModParser interface includes the following 
method (ModHandler is an empty interface):

  public abstract void setHandler (String handlerID, ModHandler handler)
    throws SAXNotSupportedException;

I propose the following core handlers, with the understanding that SAX 
parsers are not required to support any of them (they are free to
throw a SAXNotSupportedException):


ModSAX Core Handlers
--------------------

(All handler IDs correspond to a specific interface.)

http://xml.org/sax/handlers/lexical <LexicalHandler>
  Receive callbacks for comments, CDATA sections, and (possibly)
  entity references.

http://xml.org/sax/handlers/dtd-decl <DTDDeclHandler>
  Receive callbacks for element, attribute, and (possibly) parsed
  entity declarations.

http://xml.org/sax/handlers/namespace <NamespaceHandler>
  Receive callbacks for the start and end of the scope of each
  namespace declaration.


I'm not certain, but it might make sense to replace the third one with 
a read-only parse-time property.


All the best,


David
