This class represents the abstract content of an event, which may be repeated many times, once or never. For example a training course, or a play. The primary purpose is to indicate that several events will have very similar content, to aid planning what to attend. It does not indicate that there is any reason people could not attend more than one realisation. It should not be used to abstract a repeating event, such as morning coffee or a monthly meeting. Multiple Events may reference that they are realises of the same Activity. Activities are not Events and may not have a time or place.
