My pleasure :-)

My sense is that your analysis of the protocols is
  syslog
  encapsulation
  transport
somewhat RFC3411-like so we might have an enumeration for encapsulation, one (or
more) for transport and problem solved.  I am saying that the structure
(architecture/layers) is not like that (no dbh:-), that we
have 'tls/tcp/IANA port' all tied up in a bundle together, take it or leave it.
Were we ever to do anything different in future, most likely it would be a
another package, perhaps SSH/TCP/different IANA port or TCP per se, so the
decomposition you imply does not make sense to me.

Also, there is more than one flavour of syslog (-protocol, RFC3164) and perhaps
we need that specifying more than we need to specify what lies underneath.  So
option c) is the closest but may not be enough.
