DeclaredPropertyOnly

The property the element declares stands where the modifier found it, and what something else works out from that write is left where it is.

Declared where the write provokes a derivation the element does not make - a look and feel recomputing a property of its own, a collaborator resetting its state as it is installed. Which properties are derived, and from which writes, is not something the element can know: what one look and feel derives is not what another does, so no list of names can be complete.
