Automatic translation of classes to relations requires every regular, i.e. non-subclass and non-association classes, to have a primary key.

However since the i.e. clause is an interruption for clarification one might argue that ideally it would be delineated with dashes, not commas. E.g., see Parentheses vs. double commas vs. dashes to provide additional detail.
