I'm not sure what you're getting at. The law itself defines the elements that need to be present. Are you asking what specifically constitutes "ridicule" or "holding up to contempt"? I think there are centuries of Anglo-Saxon law that nail down the meanings of those terms, and I'm pretty sure they correspond well to their commonly understood meanings today.
Are words alone sufficient for conviction? If so how are those words described? You seem to not understand the concept of 'elements', those are the exact things that must be proven for a conviction and are usually quite specific.
