[Smcwg-public] [External Sender] Updates to 3.2.4.1/4 relying on signature for personal vetting

[Pedro FUENTES]

I fail to understand why we mention document signing on a BR specification that is not dealing with such EKU.

I am referring in particular to the DocuSign remote signature service in which the signatures are (commonly) always made with the same key and relative certificate whose Subject is the DocuSign company itself (and not the person signing the document). I have not spent a lot of time investigating the matter, but my understanding is that the link of the DocuSign signature with the signer is just based on a previous email exchange. An "ID Verification" step is a Premium Feature that the average DocuSign user is not obliged to buy.
