booleans and other builtin types are datatypes.

It's because I havn't added datatypes for Python yet.  The question is
should we have a standard set of datatypes for all languages and
translate them as code is exported (since UML is supposed to be
language indepenant) or have specific datatypes for each language.
The first seems more correct.

Actually I don't know if inbuild data structures like dictionarys,
lists and (in C type languages) arrays should be datatypes, I suspect not.

There seems to be a problem, when you add an attribute of type
new_class1 or whatever it tries to create a datatype for you, which it
shouldn't.
