I don't think that the examples (I presume you mean "in that section",
since the examples in Appx C aren't DNS names) are normative, and as
nearly as I can tell nothing about section 3 is restricted to the host
name syntax.  It's true that if you want to use IDNA with DANE then
you have to do it using A-labels.  I don't really get why any of that
needs to go into the protocol document, though.  This is a document
about how you do stuff in the DNS, and that means you have to do it in
a DNS-y way.  No?
