The article says "XML files should standalone". Most XML files are not readily readable unless you have looked at the XSD or copious amounts of documentation, if someone documented it, to understand the options, their meaning and their values. And, usually, XSDs are referred as schemas, just saying. Subsurface XML's are, to me at least, reasonable. Does it follow a spec? No. Can I, a human, look at it and say that 'm' stands for meters? Sure, the context is "humans diving" so 'm' can stand for miles. Being a human means I can process contextualized information. Man, I really hate XML and have some dislike for its defenders.
