-- | Accepting an optional '.' at the end of the subdomain doesn't conform
-- | to the (prefered) syntax of a domain as described in RFC 1035.
-- | However, this last '.' character should be acceptable in most applications,
-- | specially when an "absolute" name (example.com.) has to be differenciated from a "relative" name (www).

-- | PS: both "absolute" and "relative" are from filesystem's terminology,
-- | but I assume the reader to be more familiar with file-systems than DNS terminology.
