By vote of the Working Group in Redmond during the December 13-14 
face to face meeting,  I've been asked to revise the wording of
DR309.

=== From the 2000-12-19 XP Requirements WD:

>DR309 Ednote: Pending proposal. Owner: David Ezell 
>
>In cases where the contract between entities is well known, the use 
>of XP as a protocol to fulfill those application  contracts should 
>allow processing without requiring a complex XML application 
>infrastructure provided the documents  exchanged are well-formed 
>and within the tenets of the XML Infoset.

=== Proposed revision:

>DR309
>
>Following the example of XHTML Basic [1], XML Protocol should support 
>exchange vocabularies which will work on resource constrained devices, 
>including devices which may not be able to support the full feature set 
>normally associated with XML processing environments.

=== Rationale:

The idea of quoting W3C precedent for this idea is new to me, and I'm
trying to get a feel for community acceptance.  I don't think I've
changed the basic sense of the requirement.

Specific issues raised at the f2f:

a-- "tenets of the XML Infoset" is not widely understood.
b-- use scenarios are not easy to imagine. 

Other observations:

XHTML Basic (recently a proposed recommendation) is probably a good 
example of where we'd like to head with this requirement [1], and I'm
floating the idea of referencing it.  From the text:

>HTML 4 is a powerful language for authoring Web content, but its 
>design does not take into consideration issues pertinent to small 
>devices, including the implementation cost (in power, memory, etc.) 
>of the full feature set. Consumer devices with limited resources 
>cannot generally afford to implement the full feature set of HTML 4. 
>Requiring a full-fledged computer for access to the World Wide Web 
>excludes a large portion of the population from consumer device 
>access of online information and services.

Replace "HTML 4" with "XP 1.0" and it's rather close, I think.
