I am not posting another hint for Vaida Bogdan here,
rather some general discussion of the \newif approach
that has been suggested:

A minor technical remark on this proposal:
instead of \ifdocAtrue, you must type \ifdocA

With large documents or differences
(and/or too primitive source editors),
you may experience difficulties concerning
which \if... corresponds to some given \fi.
Another danger is that some inter-word space
may be missing or wrongly doubled in the output
-- unless the user is careful and skilled enough.
At least some of the packages at which this thread
has hinted help in avoiding these problems.
