Complete type name

The complete name of a group is displayed in the title bar of its window. A type's complete name is similar to a path name, beginning at the type and including all types in the path up to the root. Spaces appear between types in a complete type name.

You can have duplicate type names as long as they are not on the same level. Each type has a unique complete name, so there is no doubt as to which particular type is being referenced.
