#   Description:    This is the RPC::XML::Parser class, an empty class that

#                   be created/returned by RPC::XML::ParserFactory.
#
#   Functions:      new
#                   parse

#   Sub Name:       new
#
#   Description:    Constructor. Dies, because this should be overridden.
#
#                   Per RT#50013: Now, when called specifically for this class,
#                   quietly loads RPC::XML::ParserFactory and instantiates a
#                   parser based on XML::Parser.

#   Sub Name:       parse
#
#   Description:    Parse the requested string or stream, or return a

#                   sub-class should have overridden it.

#   Sub Name:       parse_more
#
#   Description:    When called on a push-parser instance (which may or may
#                   not be the same class), parses additional content and
#                   waits for more. In this case it dies because the sub-class
#                   should have overridden it.

#   Sub Name:       parse_done
#
#   Description:    When called on a push-parser instance (which may or may
#                   not be the same class), finishes the parse process and
#                   returns the result. In this case it dies because the
#                   sub-class should have overridden it.
