sellener, I think you are being way too literal, although a lot of that is the FAA's fault i the way it defines "known ice". But, no, you are not going to encounter ice in visual conditions, even if there is an Airmet for icing in clouds and in precipitation.

The FAA's AC is giving you a set of guidelines and examples of the types of conditions that are conducive to icing. The only significant one outside of clouds is freezing rain (although snow might be an issue in limited circumstances).

The legal standard for violations is even looser - if you flew into conditions that a pilot should have known knew was conducive to icing conditions - even if there was no PIREP for the immediate area or specific icing forecast - you can be found in violation.

Here's an example of how loose the standard can be: http://ntsb.gov/alj/alj/O_n_O/docs/aviation/5154.PDF

A violation often comes down to: if you land with ice on your wings or cause a problem because you actually encounter ice, the chances are you flew into known icing conditions.
