Followings are siles of "Requirements of Full Mode" 
which I presented at the fax-wg today.

Thank you for all comments to Mr. Rafferty, Mr. Masinter
and all attendance at the meeting.

Goals for Full Mode (1)
 RFC2542 Terminology and Goals for Internet Fax
 2.4.2 New "Internet Fax" devices
  Manufacturers may offer new devices which support 
  any combination of the roles defined in setion 2.3. 
  In particular, a device resembling a traditional 
  fax terminal, built out of similar components 
  (scanner, processor, and printer), could offer a 
  similar functionality to a traditional facsimile 
  terminal, but be designed to connect to the 
  Internet rather than, or in addition to, a telephone 
  line connection.
 4.1 Functionality
  It is desirable {3} for Internet Fax to support all 
  standard features and modes of standard facsimile.

Goals for Full Mode (2)
 4. 6 Simplicity
  It is important {2} that it be possible to use  
  Internet Fax end-to-end in the current Internet environment 
  without any changes to the existing infrastucture, 
  although some features may require adoption of existing 
  standards.
 5.5 Goals for capabilities exchange
  To support interoperability with these mechanisms, 
  it should {2} be possible to express a wide variety of 
  fax capabilities.  Capability support has three elements: 
  expression of the capabilities of the sender (as far as 
  a particular message is concerned), expressing 
  the capabilities of a recipient (in advance of the 
  transmission of the message), and then the protocol 
  by which capabilities are exchanged. A request for 
  capability information, if sent to a recipient at any time 
  other than the immediate time of delivery of the message, 
  should {2} clearly identify the sender, the recipient 
  whose capabilities are being requested, and the time 
  of the request.
