Secondly, regarding "uses of the class members", it would be extremely
useful to us to be able to see "who" calls a particular method OR "who"
accesses a particular class variable.

Every software developer on the planet, from time to time, needs to add an
argument to or change the return value of a method. In other cases you may
need to change the data type of a variable OR even remove a variable from a
class. In situations like these it is extremely important to be able to find
all the references to the particular method or variable that you want to
change so that you can properly evaluate the impact of the change you are
about to make.

So, my question then is, does Javadoc produce or gather this cross reference
information for class methods and variables like it does for the classes
themselves. Hopefully the answer to this question is yes and if so, then
hopefully I can access this information in my doclet and produce this extra
cross reference information in the Javadoc's of our system.
