RFC 3354                  IOTP V2 Requirements               August 2002


      Instead, it will be possible to propose an arbitrary sequence of
      transaction steps.

   3. Include specification of an Offer Request Block.

   4. Support Improved Problem Resolution (extend to cover presentation
      of signed receipt to customer support party, better defined
      Customer Care role, etc.).

   5. Add provisions to indicate and handle a payment protocol not
      tunneled through IOTP.

   6. Add support for server based wallets.

   The following may be include in IOTP v2:

   1. Support Repeated/ongoing payments.  For example, a means to
      specify that a customer approval covers not only the instant
      purchase but also some limited number of future purchase with some
      total or per purchase spending limit.

   2. Enhanced Server to Server messages.  For example, a means for a
      Delivery Handler to inform a Payment Handler that goods have
      actually shipped, which may be a pre-condition for making a charge
      against a credit card.

   3. Include the ability to add both fields and attributes to existing
      trading blocks in addition to the present ability to add entirely
      new trading blocks.

   The following are out of scope for IOTP version 2:

   1. Legal or regulatory issues surrounding the implementation of the
      protocol or information systems using it.

   2. Design of an XML Messaging Layer.  Instead, whatever is or appears
      most likely to become the standard XML messaging layer will be
      used.  This includes a standard enveloping, addressing, and error
      reporting framework.

   3. Design of XML Digital Signatures.  Instead, the existing standard
      [RFC 3275] will be used.
