> In SIS 0.3, {{NilReason}} are stored by implementations of the {{org.apache.sis.xml.NilObject}}
interface. However we can not implement this interface for {{Boolean}}, {{Integer}}, {{Double}},
{{String}} and other JDK classes that are {{final}}.
> The proposed workaround is to provide an internal {{PrimitiveTypeProperties}} class which
will assign {{NilReason}} to a specific instance of {{Boolean}} or other JDK classes, using
an {{IdentityHashMap}}. Inconvenient is that testing {{if (object instanceof NilObject)}}
is no longer sufficient - we now need to use the {{NilReason.forObject(Object)}} method.
