Given the use case in draft-ietf-dnsop-dns-wireformat-http, defining a new media type seems like overkill, particularly given that it will be transporting *the exact same* data as an existing media type. Instead, an optional parameter could be added to the application/dns-udpwireformat registration in the DOH document.

Proposal:

=====

In the media type definition, change "Optional parameters" to:

Optional parameters: original_transport
   original_transport has two defined values, "udp" and "tcp".
   This is only expected to be used by servers.

Also in the the DOH document, under Operational Considerations, we would add:

This protocol does not define any use for the original_transport optional
parameter of the application/dns-udpwireformat media type. 

=====

Then draft-ietf-dnsop-dns-wireformat-http could define the use of that optional parameter as it sees fit.
