Draft UN resolution on Syria chemical weapons as agreed by the U.S. and Russia and the unanswered questions it raises

The wording of the draft resolution :-

Does PP9 mean that Saudi Arabia will be investigated for supplying chemical weapons to Islamic Extremist insurgents?

This resolution is being filed under Chapter 7 which allows penalties for violations that include sanctions and the use of force.
Other reports state that a second resolution (which Russia would veto) would be required to allow the use of force, but I can't see this in the wording. Awaiting clarification.

Does clause 21 mean that UN action will be taken against the insurgents in the event that they are shown to use chemical weapons in the future?

Specifically not included is any statement that Assad or the Syrian regime was responsible for the chemical weapons attack in Damascus in 21st August (for obvious reasons - there is no credible evidence that Assad was responsible for the attack and credible evidence that the insurgents were responsible).
