We already display short statements about property semantics in the property editor assist dialog and in context help. The logic for deriving these statements is currently hardcodded. In fact it's different code for those two display sites. 

We need to have a single code path for deriving these statements regardless of where they are to be displayed. We also need this logic to be extensible.

To support these requirements a property-level FactsService should be created. A property should be able to have multiple active facts services from which to derive the full list of facts. Adopters should be able to register a facts service via standard service registration facilities (extension system or @Service annotation). To make it easier to consume facts, a FactsAggregationService should also be created.
