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

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.
