What does "exposition only" mean? Why use it?

c++, terminology

Solution

It's used to indicate one possible way to implement the particular item, but not necessarily the best or recommended way.

Problem

All over boost.org and also at other sites on the web I've seen code of this form: ``` class whatever { ... private: std::vector<std::string> m_name; // exposition only }; ``` What is the meaning of "exposition only"? What is the comment's purpose? What is it trying to tell me?
