Updated stack diagram

Apologies for being out of touch this week.  I'm actually on vacation, taking my son to visit colleges.  For some reason I thought I'd have more time to keep up with things at W3C, but it's also true that W3C things tend to get less priority than day job things...
 
Anyway, here's the updated stack diagram I intended to send last week.  This is the result of the discussion at the editor's concall April 16, in which we thought that George's diagram seemed to have the most support, with some minor changes, which I've made.  
 
David put together a collection of the various proposals, which we reviewed in coming up with the proposed changes and the consensus around George's diagram:

The minor changes to George's diagram are:
 
-- Remove the base technologies from each box and re-introduce the overlay box as Hugo had suggested it
-- Change the label on the second box from the top from "services" to "descriptions"
-- Change "transport" to "communications"
-- Add "transactions" to SOAP extensions
 
The one remaining anomoly is that SOAP and WSDL remain called out explicitly, and no other specs are.  I realize it will be difficult if not impossible to identify a finite set of specifications given the plethora available to choose from, and the lack of consensus in some areas.  Perhaps we can resolve this by taking a page from WS-I's book and putting a version number on the architecture itself.  So we can say "SOAP and WSDL and (whatever)" are included in V1, etc.
