- Move annotation value service, annotation value provider base classes and annotation extension point to org.foritss.tooling.base
- Remove createEditingSupport() from IAnnotationValueProviderBase and move functionality to org.fortiss.tooling.base.ui.annotation.editingsupport.EditingSupportFactory instead
- Rename extension point to org.fortiss.tooling.base.annotation.

Example binding:

<extension point="org.fortiss.tooling.base.annotation">
  <annotation binding="org.fortiss.af3.timing.annotation.valueprovider.CIValueProvider">
     <modelElementClass modelElementClass="org.fortiss.af3.component.model.Component"/>
  </annotation>
</extension
- Adapt all known users of annotation framework to new structure
- The change is a preparation to fix #2208, i.e. to put the instantiation of a model element and its annotations into a single undo/redo command
