Call for Consensus (CfC): Publish First Public Working Draft of WebRTC-SVC

This is a Call for Consensus to publish the editors' draft,
https://w3c.github.io/webrtc-scv/ <https://w3c.github.io/mst-content-hint/>, as a First Public Working Draft.

The CfC will last for one week, and end on Thursday, October 10, at 16:00 UTC

In response, please state one of the following:

- I support publishing the current webrtc-svc as a Working Draft

- I object to publishing the current webrtc-svc as a Working Draft, due to issues filed in open bug <#number>.

Harald, for the chairs
