/** A property may not be both 'readonly' and having a memory management 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. So, do not issue any warning on 'readonly' and memory management
attributes in a property.
