Date Mon, 24 Aug 2009 06:24:59 GMT

--------------------------------------

Doug said:
>The implication on documentation should be something like:
>    * Public/stable should be documented.
>    * Public/evolving should documented, but must be well-marked as evolving.
>    * Private, limited or otherwise, should not be included in public documentation, but
only in internal documents.

Agreed, However private/stable and private/evolving also need to be document even though they

are not visible in the public documentation, only in the developer documentation.
Developers need to understand which private/internal interfaces are stable since their stability
needs to be maintained across releases, For example the client protocols need to be stable
even though they are
private for wire compatibility.
