- This will be performed by the IElementCompositorService that is called from createNewSourceDropContext().
- Doing it here already, will trigger an expensive check for duplicate IDs when the ID assignment is issued for the second time from the IElementCompositorService

- I.e., do this for each specification instead of the "contained" model element. Since
"contained" might already have an any, this would trigger an expensive algorithm to
check if there are duplicated IDs.

- getReferencingResourceURIs(): Load side-car model resources via ResourceSet.getResource. This has the advantage that custom resource factories will be considered

- Performed some refactoring (no functional change) and added documentation

- prepareAnnotationEntry(): Comment out warning in case the annotation has not been instantiated yet. In the current situation, it has a performance impact on model transformations.

- prepareAnnotationEntry(): Emit a warning in case the annotation has not been instantiated yet. The goal is to remove the code that instantiates the annotation on the fly in the long run.

Ensure that IDs have been assigned to all new model elements before they are hooked to the project / resource
- Rationale
  - Model elements for which no ID has been assigned, have id 0 (which is the default value). 
  - When the new element is hooked to the resource, ResourceUtils.KernelResourceFactory.KernelXMIResource.getId() is called, which internally calls setId() to synchronize the XMI ID with the AF3 ID. In case the ID is still 0, this implicit call will corrupt the ID -> model object map (by override the mapping for key 0).
- Changes
  - ElementCompositorService: Assign IDs *before* hooking new element to the container (but of course using the container to determine the next free ID)
  - ModelElementCompositorBase: Assign IDs to newly instantiated annotations
