I'm not sure what you are suggesting, but I think it is along the lines of "merge XACML profile back into framework document" and "create a provisioning document". If so, the WG already decided to make the XACML profile separate, so unless we have new information, we should not revisit that decision.

If you have something else in mind it might be clearer if you note the rough outline for the various documents.

Regarding provisioning, it is out of scope, especially with respect to policies:

"The management of security policies (e.g. by remote entities) is out of scope of this group."

In general, an end-to-end solution is appropriate to privacy, security etc. For example, considering all aspects, business, legal, regulatory, CA operation, certificate distribution, key management, provisioning, etc etc.  We cannot do all this, so yes our scope is limited to an aspect of the system.  Not much to do about that, though in some sense it makes the work of the WG that harder while also giving us  a chance to finish.

What we can do is recognize the critical aspects about what we do that relate to other system touch points. If you have any ideas please share them on the list.

Thanks
