When updating the SID model you should follow these guidelines:
- Follow guidelines in GB922-1U User Guidelines
- All entities/attributes should be defined
- All attributes should be public, including role attributes for associations
- Naming conventions for association names should be followed
- Naming convention for association classes should follow the association naming guideline that uses the names of both entities involved in the association
- Use tipAttribute - support stereotype to specify if an attribute is optional/mandatory (you can find more information on tipAttribute stereotype in the TIP Profile page)
