I can see why a text format was adopted, I'm sure that there were lots of people clinging to the idea that the data ought to be editable in vi if necessary. I happen to think that editing data files by hand is not a smart thing to do, because it encourages people to fix symptoms instead of causes.

Thankfully XML developed sufficient complexity to effectively discourage that. A naive user who looks at XML for the first time is going to be baffled. That's not in itself a good thing, but it has some benefits.

The efficiency argument I've already covered, but I should add that it's normal for XML files to be compressed, which effectively turns it into an efficient binary format.
