It is the vagueness of the term "compiler support", which you did not alleviate in your answer, which I am trying to clarify.
"Compiler support" means "anything the compiler can give us so that we can implement that class correctly".
It could be a specially-recognized preprocessor define, a quasi-class (e.g., SGI's type traits), a pragma, a keyword, or anything else that the compiler provides.
Yes. "Compiler support" can be seen as a courtesy by library experts, so they aren't trying to tell core language experts exactly how to do something.
Shouldn't the compiler support mechanisms for the type_traits library be documented so that users of a particular compiler can understand which type_traits functionality works for them ? It is information that is needed not only by other Boost developers who use type_traits in their metaprogramming work but by users of the implementation also.
