@abc.abstractmethod<EOL><INDENT>def match_value_syntax(self, syntax, match):<DEDENT>
pass<EOL>
Adds a match for parameters of a given value syntax.

        Multiple matches can be added to perform a boolean ``OR`` among
        them.

        :param syntax: the parameter value syntax
        :type syntax: ``osid.Syntax``
        :param match: ``true`` for a positive match, ``false`` for a negative match
        :type match: ``boolean``
        :raise: ``NullArgument`` -- ``syntax`` is ``null``
