That is, no explanation *in English*. If we both speak Greek, I can
explain it in Greek, using the fact that English and Greek are both
natural languages and translation is possible. Of course, the Greek
explanation will be far more verbose, but that doesn't affect the

You are ignoring my concrete example. How would you *in general*
program an interpreter of diagnosis vs. cure based on the medical
record with obfuscated field names that I posted?

What does XML with obfuscated names convey that CSV does not, other
than nesting? It seems to me that you can do just as much with:

No more so than any other serialization syntax. XML has the advantage
of having standard parsers, but so does ASN.1.
