RE: [XCON] CPCP Requirement: Hidden Participants

We thought of that just before releasing the new requirements draft. We concluded that hidden user policy can be local implementation since the moderator of the conference who sets the policy and decides who is hidden and not could be the terrorist himself. Therefore we concluded that hidden users must be allowed by network administrators for any conference and must not result is a modification to the conference policy.
