NIT: I think the abstract should mention any IANA registries created. Section 2: DNS resolvers that serve the DNS protocol and non-DNS protocols at the same time might consider .alt like an entry in the "Transport- Independent Locally-Served DNS Zone Registry" that is part of IANA's "Locally-Served DNS Zones" registry, except that .alt is always used to denote names that are to be resolved by non-DNS protocols. I'm not sure what this is not written simpler: DNS resolvers that serve the DNS protocol and non-DNS protocols at the same time MUST resolve .alt names using the non-DNS protocols. On wireformat, you say: Note that using .alt as a pseudo-TLD does not mandate how the non-DNS protocol will handle the name. If the non-DNS protocol has a wire format like the DNS wire format, it might append the null label at the end of the name, but it also might not. This document does not make any suggestion for how non-DNS protocols deal with the wire format of their names. My concren is if a DNS resolver supporting alt names makes it selection based on wire format and not string (presentation format). We want to avoid the string to be seen as a non-FQDN that needs an FQDN appended. So I think we might need to be a little more subtle here? This document creates an IANA registry for specification documents that use the .alt pseudo-TLD. I still believe the whole point of .alt is to give people a non-DNS space that IETF stays out of. I do not think it should create or maintain a registry for this. Security Considerations could say that .alt queries MUST NOT be forwarded to other DNS servers for resolution. Or perhaps it could state DNS resolvers MAY use special handling of .alt queries as to only query for the non-existence of the .alt TLD and MUST NOT send second level domain queries within the .alt TLD to other DNS servers.
