    >Description:

    As discussed in issue 226, tools accept mintypmax expressions
    as the values of parameter assignments, even if they are not
    surrounded by parentheses. The same is true for defparam
    assignments.

    In A.2.4, should

        defparam_assignment ::=
             hierarchical_parameter_identifier '='
                constant_expression

    be replaced with

        defparam_assignment ::=
             hierarchical_parameter_identifier '='
                constant_mintypmax_expression

    ?
