final PageElementCachePolicy.PolicyResult	shouldClearCache(String workspace, Site site, String pageElementType, Event event)	First pass of event processing, at the type level. Returning NEED_MORE_INFORMATION eventually leads to the second pass, which is more precise, and also depends on a particular element, but is more costly to compute. Returning null means that this policy declares itself as not concerned by the current event.
