But there are nothing about parsing and interpreting it in any way. The
whole brand string is mentioned as identifier but not parts of it. :-\ So
we have to "cast" it into our numerical identifiers in some way. And such
casting cannot be strict and robust in any way.
The Question is: Are we need this BeOS legacy numerical identifiers? May
be only brand string will be enough?
