One of the earlier details added to the Wikibook.

Currently I'm using the Oberon subsystem in Guenter's LinuxA2 Generic.  
This is copied from Oberon.Texts.Mod .
MODULE Texts IN Oberon; (** portable *)	(*JG 23.8.94*)
    ...
    TextDesc* = RECORD (Objects.ObjDesc)
      len*: LONGINT;	(** Text consists of characters 0 to T.len - 1. *)
      obs: Objects.Library;	(* Library containing objects located in text. *)
      trailer: Piece;
      org: LONGINT; (*cache*)
      pce: Piece
    END;

So appears to be the Oberon context.

Martin Reiser's _The Oberon System_, page 139 has this.
TYPE
  Text = POINTER TO TextDesc;
  TextDesc = RECORD
    len: LONGINT;
    notify: Notifier
  END;

That is Legacy Oberon or another?  Certainly not the Oberon context above.  

Thanks,                         ... Lyall E.
