In other words, we can only rely on convention and the good behaviour of the coder to respect the constness of objects passed via their pointers. It's a step backwards from the old kcal interface in this respect, where the compiler enforced no modifications on direct members of the const object.

Using the standard kcalcore API, there's now no way to indicate whether objects passed via pointers are const or not.
