Subject: SOAP Confidentiality and Integrity: Next Step?

This email is a final step in a thread in how to start work on providing 
confidentiality and integrity for SOAP messages. I've discused a range of 
security issues [1] with a conclusion that this topic (soap+xmldsig+xenc) 
is most pressing; however, I was not able to find agreement that this issue 
should be shoe-horned into an existing WG, instead it should be part of the 
Web Services security. [2]

Though I'm relatively ignorant of the ws-arch discussions, I've heard the 
ws-arch WG is considering this issue and will try to have charters 
available for work in July [3], but that the immediate issue might also be 
delayed be consideration of the bigger issues. Consequently, I'd recommend 
that a charter for work in the WS Activity be specified with a scope no 
larger than [4] -- and potentially more narrow (e.g., without tokens). A 
"web services security" community does not yet exist (or it does, but it's 
fragmented) and starting work on this immediately not only commences with 
the work, but helps build a community which then can contribute to the 
larger discussion. For instance, because standardized security components 
do not yet exist, specifications such as XKMS [5] may end up specifying 
"one-off" versions in the short term. However, these could be contributed 
to the WS work. We all know somebody who knows somebody who is in the other 
WG, but sometimes that isn't quite enough. <smile/>

In conclusion, I advocate a charter with specific and immediate terms, and 
an active recruitment of participants. Please let me know if and how events 
are likely to be otherwise. Thanks!
