[sv-cc] vpiVirtualInterfaceVar and vpiClassVar as vpiRefObj

Hi All,
I was thinking about part of LRM:
 
"A ref obj represents a declared object or subelement of that object that is
a reference to an actual instantiated object.

A ref obj exists for ports with ref direction, for an interface port, a
modport port, or for formal task function ref

arguments. The specific cases for a ref obj are as follows:

- A variable, named event, named event array that is the lowconn of a ref
port

- Any subelement expression of the above

- A local declaration of an interface or modport passed through a port or
any net, variable, named event, named

event array of those

- A ref formal argument of a task or function, or subelement expression of
it 

"

I have an example:
 
 
module top;
 class C;
  int i;
 endclass
 function automatic void afct(ref C c);
  $vpiF(c.i);
 endfunction
 
 C x=new;
 
 initial #2 afct(x);
 
endmodule
 
Is "c.i" really a ref object ? "i" is a part of vpiClassObj not vpiClassVar.
Should LRM exclude from being ref object class and virtual interface
member's ?
 
Regards,
Radek
