@discussion This class defines what Internet messages are composed of.
An Internet message is composed of various parts which can
be text parts, images, PDF documents and so on. Even a message
is a part, with additional headers (like "From:", "Subject:"
and so on). CWMessage is a superclass of CWPart.
