NAME
       XML::SAX::Exception - Exception classes for XML::SAX

SYNOPSIS
	 throw XML::SAX::Exception::NotSupported(
		 Message => "The foo feature is not supported",
		 );

DESCRIPTION
       This module is the base class for all SAX Exceptions, those defined in
       the spec as well as those that one may create for one’s own SAX
       errors.

       There are three subclasses included, corresponding to those of the SAX
       spec:

	 XML::SAX::Exception::NotSupported
	 XML::SAX::Exception::NotRecognized
	 XML::SAX::Exception::Parse

       Use them wherever you want, and as much as possible when you encounter
       such errors. SAX is meant to use exceptions as much as possible to
       flag problems.

CREATING NEW EXCEPTION CLASSES
       All you need to do to create a new exception class is:

	 @XML::SAX::Exception::MyException::ISA = (’XML::SAX::Exception’)

       The given package doesn’t need to exist, it’ll behave correctly this
       way. If your exception refines an existing exception class, then you
       may also inherit from that instead of from the base class.

THROWING EXCEPTIONS
       This is as simple as exemplified in the SYNOPSIS. In fact, there’s
       nothing more to know. All you have to do is:

	 throw XML::SAX::Exception::MyException( Message => ’Something went wrong’ );

       and voila, you’ve thrown an exception which can be caught in an eval
       block.
