7 * string indicating the party (eg, the party name plus some machine
8 * identifier), optionally followed by an "_", and more characters to make the
9 * partyid unique. We require the name and "-" so that the string up to the
10 * first "-" can be used to determine between sessions which opponents are
11 * instances of the same class.
12 * <h2>Note</h2> Normally, negotiation parties should not create new Party IDs
