This implementor agreement, related to the negotiation of message size during Initialization, was approved at the October, 1996 ZIG meeting in Brussels.

This agreement adopts the following semantics:

• If the client supplies values of zero for both parameters, then the client is explicitly indicating "no preference". (It is recognized that the server values overide the client values anyway; this would be useful in the circumstance where the server might use the client supplied value to help determine the response value). Note, this agreement adresses only the case where the value of both parameters is zero. It does not address the case where one value is zero and the other is non- zero.
• If the server responds with zero for both parameters (regardless of what the client proposed), the server is indicating that the client must be prepared to accept arbitrarily large records and arbitrarily large messages. As above, this adresses only the case where the value of both parameters is zero.
