A server must not rely on values sent from clients to be within the bounds a parameter specifies. It needs to pre-evaluate a value-update and either:

  • reject the update
    • A rejected value must not be sent to other clients and the current value needs to be sent back to the client.
  • confine the value within its bounds (clip, scale, do-nothing, ...)
    • A corrected value is to be sent back to the sending client.

This shall not be part of the protocol specification but server implementers need to consider this.
