This document should not be published, per WG and IESG consensus.
The reason is that the WG reached consensus that 3-in-1 should be the only encoding going forward.
Publishing this draft would be confusing.

Pre-congestion notification (PCN) is a mechanism designed to protect the Quality of Service of inelastic flows within a controlled domain. It does this by marking packets when traffic load on a link is approaching or has exceeded a threshold below the physical link rate. This experimental encoding scheme specifies how three encoding states can be carried in the IP header using a combination of two DSCPs and the ECN bits. The Basic scheme only allows for three encoding states. The Full scheme provides 6 states, enough for limited end- to-end support for ECN as well.
