Hi Marty, Thank you for your comment. I am answering on your second point in this message. I think our intention on the requirement level to the mutual authentication is same with you. Although the informational description of the constraints is described by using the words "will be required", the constraints which are normative statements state that the requirements are "SHOULD" which is one level looser than "MUST". I think we can change the word "required" to "recommended" in the informational sentence, if it is confusing.

I assume that this document has not entered public comment, so I'll post my comments here regarding security. I'm afraid that these are largely the SAME comments that I've made before.
Here are my specific concerns...
The security section (section 8.1) implies that *EVERY* SOAP message must be either (1) over TLS or (2) "SOAP Message security with XML signature and/or XML Encryption". If you truly mean this (implied by "R0811"), this is overly restrictive and makes no sense (there does not exist *ANY* message that can justifiably be sent between services/clients that need not incur the overhead of crypto?). However, it's not clear if you really mean this ("R0819", "R0820", "R0821", "R0822", "R0823" seem to imply otherwise)... so, what exactly is the intention here?
In general, section 8.1.2 is too restrictive -- "mutual-authenticated WS- Communication will be required" is overly restrictive. And this section includes this statement: "The Profile mandates that there be no anonymous communication. To ensure interoperability, only X.509 certificate-based authentication is permitted by the Profile.") So, this latter part in particular says that there is *NO PLACE* for password authentication in OGSA. (I also believe that you have now outlawed MyProxy, right?)
Am I reading something incorrectly?
