class PartyId:
        '''
        Unique ID of a party in a negotiation. The name should start with a short
        string indicating the party (eg, the party name plus some machine
        identifier), optionally followed by an "_", and more characters to make the
        partyid unique. We require the name and "-" so that the string up to the
        first "-" can be used to determine between sessions which opponents are
        instances of the same class.
        <h2>Note</h2> Normally, negotiation parties should not create new Party IDs
        as all needed IDs should be provided by the protocol.
