The top-down analyzer is an optional preprocessor to the delaborator that aims to determine the minimal annotations necessary to ensure that the delaborated expression can be re-elaborated correctly. Currently, the top-down analyzer is neither sound nor complete: there may be edge-cases in which the expression can still not be re-elaborated correctly, and it may also add many annotations that are not strictly necessary.
