I'm not sure where the best place for it is; but I'd suggest not putting
this on every directive, but only marking the few that don't follow the
common inheritance rules.

And then have an obvious document which describes what the common
inheritance rules are.

It would probably be something like the content linked from
http://blog.martinfjordvald.com/2012/08/ but could be simplified to
"inheritance is per-directive, and is all or nothing. The following are
'nothing'; the rest are 'all'. Exceptions are noted in the per-directive
documentation (and possibly listed here too)."

In the blog above, it indicates that "Action" directives do not inherit
-- I don't know if that's a useful distinction that could be made in
the documentation; it would presumably be extra work to ensure that
every directives is categorised as "inherit all", "inherit none", or
"exception", and I can't tell whether the benefit would be worth the cost.

To me, that's not special for add_header -- that's common to all
inheriting directives bar the few exceptions (root/alias, allow/deny,
and xslt_param/xslt_string_param in stock nginx).

Maybe it is easier to put it in all directive documentation, though,
if that's what people are more likely to read.

I won't be the one doing the work, so I'm not in the right place to
judge what work should be done :-)
