This is the summary of the 'Consistency' goal. Still, very little 
traction... So most of the below is my fault.


Original Goal: 

"To develop a standard reference architecture for web services 
that is consistent with the existing web and its heterogenous 
environment and distributed architecture to the greatest extent 
possible."
 
Proposed Goal:

"To develop a standard reference architecture for web services 
that is consistent with the existing web to the greatest extent 
possible."

Proposed Critical Success Factors:

CF1) The Web Services reference architecture complies with the 
architectural principals and design goals of the existing web. 
Derived sub-goals:

CF1-A) universal identifiers
CF1-B) simplicity
CF1-C) opaqueness
CF1-D) decentralization 
CF1-E) statelessness
CF1-F) scalability of component interactions
CF1-G) generality of interfaces
CF1-H) immediate deployment of components
CF1-I) intermediary components to reduce interaction latency
CF1-J) enforces security
CF1-K) encapsulate legacy systems
CF1-L) caching semantics (?)
CF1-M) platform independence

CF2) The Web Services reference architecture recommends the use
of existing web technologies which adhere to the above principals 
and which provide clear functional coverage of the responsibilities 
and constraints for a component identified in the reference
architecure. Derived sub-goals:

CF2-A) Use of a standard identifier technology (URI)
CF2-B) Use of a standard transport technology (HTTP/S over TCP/UPD/IP)
CF3-C) Use of a standard data encoding technology (XML)


Note that this is a first cut at CSFs. There is assuredly overlap 
with other goals here. By its nature, this goal is more of a 
meta-goal...
