In apt, Declaration information about a type can be gotten from the source file for the type or from the class file of the type. There can be differences in the information returned from these two views including:

* lack of source retention annotation from class files

* lack of source position information from class files

* potentially different modifers for some constructs

  * strictfp-ness of a class

  * final-ness of a parameter

  * protected, private, and static on classes

These differences need to be documented and/or compensated for.
