Unless I misunderstand this, the program still has to know, or be told, that the (string!) arguments have to be translated/interpreted as the specified "objects". It is not the case that the code can look something like
main(argc, argv)
{ int i;
i = argv[2];
...
}
when called with, e.g.,
$ foo -argument '<integer>1</integer>'
We maybe should have resorted to a specific example earlier in this thread, to help the discussion.
Do we agree on this? Am I missing something (like a change in the technology since last I waded into this area)?
Christian: is this something like what you are asking about? If not, can you give a short snippet that shows what you want?
