Before we move to coding the similarities, differences, and risks into the document, it would be useful just to generate a complete list within this WG. It would certainly be a breach of trust to omit information from the document, if done for the purpose of hiding tree walk limitations. Doug

Let's talk through the selling process for the Tree Walk algorithm. Who are our Stakeholders? There are three main stakeholder groups for DMARC: Senders, Intermediaries, and Evaluators.Senders and Intermediaries just want to ensure their messages get delivered. Evaluators have the
