/** Normally, a property cannot be both 'readonly' and having a "write" attribute
(copy/retain/etc.). But, property declaration in primary class and protcols
are tentative as they may be overridden into a 'readwrite' property in class
extensions. Postpone diagnosing such warnings until the class implementation
is seen.
