SAX-ext proposal #5: DefaultHandler2

[David Brownell <david-b@pacbell.net>]

DefaultHandler infoset extensions

- The standardized extension handlers are not supported by the
  DefaultHandler class.

- That means that applications (or libraries) that need to pass
  that information need to provide/use a class of their own.

PROPOSAL

    - Define a new org.xml.sax.ext class implementing those two
      interfaces, inheriting from org.xml.sax.helpers.DefaultHandler

 public class DefaultHandler2 extends DefaultHandler
     { ... }

      [
 Example:  gnu.xml.util.DefaultHandler, and similar
 versions used with all versions of AElfred2
      ]

QUESTIONS:

    - Is a new implementation class really needed?  Alternative:
      update DefaultHandler.  (Meta-2)
