My concrete example was of a file inside a (say ZIP) archive.

There is no URL scheme for this AFAIK. You cannot use file: for
it when you are sitting on a plane or connected to the internet.
Unless some scheme is devised and implemented, or a CGI script
or query script installed, that data is not accessible by a system
identifier. That data is not accessible because the platform (WWW
URLs) does not support it (at that time and place).
