Subject: RE: [dss] Compound operation Verify & Sign
Nick and Co, The last suggested position I remember getting consensus on was that the request for the secondary or ancilliary operation should be expressed in the "Options" or "ProcessingOptions" structure as it was then called. So in your example below, the principle operation is the "Verify". The client requestor must express their desire through use of (for example) an "AddContentTimeStamp" option or something similar. This may necessitate additonal "Outputs" but the protocol is nicely able to handle that. As it pertains to the EPM, we have need for several such compound operations, but we will use our profile extension to express them. I also remember discussing that additional and/or optional "outputs" and "results" would be expressed by the requestor as "options". I'll dig up the references if you wish.

I believe that such an operation is important in a number of use cases, for example, notarisation services. This was brought up at the F2F meeting and was included in the requirements document (3.9). My recollection of the discussion on 22 Sept is that the only compound operation that was needed would be VerifyAndSign, although I see no record of it in the minutes. How do we envisage VerifyAndSign being supported in the DSS protocol? Is there a way of combining the two request / response structures, or do we need to define a specific structure which is this combined operation?
