[sv-ec] RE: class extending from fwd typedef?

I believe this is legal. Section 8.24 includes this:

When a type parameter or typedef name is used as a base class, as in class D4 above, the name shall resolve
to a class type after elaboration.

Subject: [sv-ec] class extending from fwd typedef?

I was reading mantis item 1500. It seems that it originally was intended to limit where you could
used a datatype which was declared as a forward typedef.
My reading of the resolution is that it i snow legal to use the type name of a fwd typdef as the base type of a
derived class.

I mean that the following is legal.

program top_level;

typedef class cds_madeup;

class cds_callback extends cds_madeup; // legal

endclass : cds_callback

  class cds_madeup;
  endclass
endprogram

Can someone confirm my understanding?
