If we agree on the file being a XML file.

Could be:
"99874987kjhk", "gnygngyasdada"
"","What is this?"

Unless you have the information that it is a CSV file, and that the first line is the CSV header (just as you need to know that it is a XML file.)

What I am trying to say, is that the quote "XML is selfdescribing" is wrong and unproved.

It should maybe read: "XML has, as e.g. also CSV files and other formatted files, support for adding field descriptors to the data. If this is used in a consistent and well-documented manner, it will support the understandability of the XML or CSV files."

-Mike: Good point. I bet that the Excel XML file could be quite unreadable.
