    #   / type-param / geo-parameter / tz-parameter / sort-as-param
    #   / calscale-param / any-param
    #
    # Although the param name definition has a list of possible values the
    # `any-param` pattern (which includes the `iana-token`) pattern is the least
    # common denominator. It basically allows param name to match anything that
    # follows the `1*(ALPHA / DIGIT / "-")` pattern. Therefore that's all we
    # validate against.
