The standard of matter chart does not pretend to try to enumerate them and cover all
The standard of matter chart does not pretend to try to enumerate them and cover all. Instead of that, it identifies the need for some forms of name (which have semantics in particular important and universally included/understood) to be defined in a standardized way, so applications to be able to do something of signicatif with them, and at the same time the need for freedom and extensibility complete to be able to define the named types specific to the application.
