This is actually not RFC7273 compatible, it should look like this
instead.

a=ts-refclk:ptp=IEEE1588-2008:0

I guess some fallback handling for Ravenna can easily be implemented
here then once everything else is in place.

That's RFC7273 compatible.

These two would be added automatically by the payloader, i.e.
rtpL24pay. However currently it does not add this and RFC3190 also does
not mention it.

Might be worth adding. Would you mind filing a bug at
  https://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer
about this?

That's automatically handled by gst-rtsp-server and you can override
these things with its API.
