The document candidly categorizes itself, in Section 1, as “a pedantic network
protocol description”. As such, I think it might be appropriate for it to
describe DNS names as appearing in the only form that is unambiguous and
implementation-agnostic, i.e. dot-terminated FQDN.
Having said that, even RFC 1034 admits that the non-dot-terminated form “is
often one where the trailing dot has been omitted to save typing”, so if the
document wants to give a nod to how DNS names are typically represented in
practice, that would also be fine, albeit slightly less pedantic.

You can compare what's in section 3 (Data structure) to what's in RFC
1034 section 3.1. (Name space specifications and terminology).
I'll post revisions weekly. Reviews and participation (preferrably first
in the form of discussion to prepare a list of things to do) are
welcome.

3. Data Structure
...
A DNS name is printed as a concatenation left to right of the
individual labels on the path from the node to the root, each label
trailing with an ASCII period '.' character. Thus a complete printed
DNS name ends with a period character.
Not exactly. There is no period after the zero-length root zone.
The last period is actually between the tld and the root zone.
So 'there is a period between each zone' not 'after each zone'
even though it looks like a trailing dot.
