But the point is: At a certain stage the server has finished reading all 
configuration options. You would be able to detect that

ns_section milly/vanilly

is a section you have no knowledge of or no use for:
"unknown config section"

This is of course only true when it is really not used, e.g. at a later point 
in time by  an "external" TCL module.

If, during startup, a configuration value is requested for the first time, the 
value OR the default value is set. This knowledge is buried in the C call:

    nsconf.shutdowntimeout =
        Ns_ConfigIntRange(path, "shutdowntimeout", 20, 0, INT_MAX);

A list of all options, btw., is created then the server logs debug notices.

As it is possible to list all options of all sections (from C and TCL), at the 
end I can detect config options that I did not request and set during 
startup.
Therefor I can lookup if the options belong to other sections or if the 
options are unknown in a section or totally unknown.

This should be possible! The question is, if it makes sense, as only options 
are detected that are requested and set during startup and TCL module ones 
will be missing.
