Hi Paul, We implemented the change and used DNS over mutually TLS (DomTLS) to represent DoT and XoT. We do believe we have address all your concerns for this draft and your DISCUSS can be lifted. The other document has its own DISCUSS and I do not believe there is any need to hold a DISCUSS. Of course, the DISCUSS being raised does not mean no changes can be made.
