Since essentially you're asking about property syntax, please read the
corresponding chapter of the manual.

If you do that at the same level (old-non-lang-specific,
non-lang-specific, lang-specific) then yes.

You can only override a header argument, not change it.  Again, if you
do this at the same level and there are other header arguments at that
level, then the + variant is what you want.

Are you aware that this doesn't quite do what you think it does, some of
the time, when things become more complex than your example?

If you maybe had an example of what you're trying to do instead of
asking stuff about things you don't want to do?  Otherwise, have a look


and adapt to your needs.
