Yes, there is no clear documentation on where and how such hooks are invoked. Including this information in the hook documentation would be a very useful addition.
Well, if it can be done. It is quite impossible to tell without knowing what exact modules you have installed (having what exact source code with them). Any contrib module can call and define hooks. True, having a documentation on what core hooks are called where would be useful, given it is updated as Drupal moves along. Goba
