Hi, Stefan:

Yes, it is, and such a config is allowed in the following section of
draft-chen-radext-identifier-attr-02.txt. 

----
2.2. Status-Server Considerations

   Unless specified by configuration, a client MUST NOT send a RADIUS
   packet (other than the Status-Server request) with the "Extended
   Identifier Attribute" to a server until it has received a response
   from the server confirming its support for the Extended Identifier
   feature using the "Extended Identifier Attribute".

Thanks.  -- Enke
