I HAVE looked at RFC 3330 and I noticed the following text in it:

   192.0.2.0/24 - This block is assigned as "TEST-NET" for use in
   documentation and example code.  It is often used in conjunction with
   domain names example.com or example.net in vendor and protocol
   documentation.  Addresses within this block should not appear on the
   public Internet.

In fact the title of the RFC is "Special-Use IPv4 Addresses" so I'm
not sure what you mean when you say that no such RFC exists for 
IPv4 addresses.
