'instance_name and 'path_name for dynamically allocated protected type

LCS2016_032 extends 'instance_name and 'path_name for protected type variables to "include the package or full instance path to the variable of the protected type". However LCS2016_014a allows us to allocate instances of a protected type dynamically without an associated variable, so what should the value of these attributes be in that case?

entity protected13 is
end entity;

architecture test of protected13 is

    type t_test is protected
        impure function get_path return string;
    end protected;

    type t_test is protected body
        variable v : integer;

        impure function get_path return string is
        begin
            return v'path_name;
        end function;
    end protected body;

    type t_test_ptr is access t_test;

    impure function make_test return t_test_ptr is
    begin
        return new t_test;
    end function;

begin

    p1: process is
    begin
        report make_test.get_path;
        wait;
    end process;

end architecture;

NVC currently prints :protected13:make_test[return t_test_ptr]::v (i.e. the path to the point where it was allocated, with an empty name).
