3. Register data type(s) in data type registry
In the following steps, Data Types which were not found in the DTR, e.g., marked as Extend or Create in your checklist, have to be registered at the DTR. This is done in a reverse order starting with missing Data Types at the lowest hierarchy level. In our case, we start with registering the permission Data Type in order to be able to proceed with defining the aclEntry Data Type and so forth.
