Explanation
Indicates that the use of the name or entity declared with this attribute is allowed, but discouraged for some reason.
This attribute is allowed in declarations of classes, typedef-names, variables, non-static data members, functions, namespaces, enumerations, enumerators, and template specializations.
A name declared non-deprecated may be redeclared deprecated. A name declared deprecated cannot be un-deprecated by redeclaring it without this attribute.
