• ID element will be a URI, not a user_at_domain NAI
• Impacts examples and various other parts of text
• Single value for sphere, no registry
• Unclear matching rules and format of domain TBD
  resolution

Anonymous

• Common policy has no condition for anonymous,
  neither does pres-rules
• Has appeared in BOTH in the past
• You can specify a rule that applies to all
  unauthenticated users, which will apply to
  anonymous ones too
• Only a limitation if you want rules to apply
  separately to anonymous users than unauthenticted
  ones
• This KEEPs coming up
• Can we please punt?
• Wait for draft-rosenberg-sip-identity-privacy to
  provide a canonical way to express authenticated
  anonymous identities

Plan

• Hannes to revise common-policy
• Pres-rules to follow, will verify schemas and
