Feedback welcome on a proposed new specification aimed primarily at certificate rollover in B2B:

The ebCore Agreement Update specification defines message exchanges and an XML schema to support the exchange of agreement update requests and positive or negative responses to such requests. The main initial application of the specification is the exchange of X.509 certificates for certificate rollover, but offers extensibility for other types of updates. The specification is based on the concept of communication agreements and the creating of new agreements as independently identified updated copies of existing agreements. The specification supports ebMS2, ebMS3 and AS4 but can also be used with other protocols that have a concept of communication agreement.
