>I'm more than a little suspicious as to why you'd ask. Would you care to explain what it is you're doing in more detail? Absolutely! I'm working with a conceptual work-flow system where indivual sumbissions are signed unsing locally known PKIs (employee-certs). These submissions are achieved. After that the signature is removed and placed by a visual indication that the signature and certificate was indeed checked by the work-flow app at a specific time. Next the submission is put in a PDF container document which is signed by the workflow engine and uses a PKI that is on legal-entity level only. Such PKIs can be created with relative ease like SSL PKIs making trust establishment easier. Now the submission can (if so is required) be transmitted to a larger audience through the workflow system. By removing the local PKIs, you don't get warnings and such which effectively *reduces* the trust in a document compared to an unsigned ditto :-| Enclosed is such an example which though still has the client signature...
