This message was posted to the RLTC requirements list. I presume something similiar will be proposed to the WSSTC when it is formed. It may be a useful exercise to consider to what extent SAML or SAML+XACML or SAML+XACML+something else can address these requirements. Obviously, it is also possible to question certain aspects of the requirements themselves. For example, I would assume point #12 under richer scenarios is controversial. Hal
