The first thing a PKSA needs to do is to open a WebSocket connection with a HAS server. Once connected, the HAS will send a

version: HAS source code version
protocol: HAS protocol version
A PKSA should decline to connect to a HAS infrastructure whose protocol version is greater than the one it supports.
