The way I read the ABNF in the spec:

domain-end = ( "." toplabel ) / macro-expand toplabel
= ALPHA / ALPHA *[ alphanum / "-" ] alphanum ; LDH rule (See
[RFC3696])
the spec doesn't allow for the dot on the end.
Is this an intended departure from standard DNS syntax explained in
RFC 1034 section 3.1??
Yes. Actually, the domain MUST be a FQDN ala SMTP. In particular,
relative names are NOT allowed. E.g. :
example.com IN SPF "v=spf1 a:mail -all"
Gives a PermError, because "mail" is not a FQDN. The above should probably be:
example.com IN SPF "v=spf1 a:mail.example.com -all"
