   sandbox

     In |project|, "sandbox" refers to the :file:`proto/sandbox`
     directory and the contained data definitions which are considered
     experimental. Such definitions are generally subject to change,
     removal or deprecation without further notice. In addition,
     promotion to the :term:`stable` area is possible.

   stable

     In |project|, "stable" refers to the :file:`proto/stable`
     directory and the contained data definitions which are considered
     ready for production use. These definitions can only depend on
     other stable definition and are subject to slow and careful
     modification and sometimes deprecation.
