It's perverse because they've taken an extra step to throw away
information that is useful in a wide variety of information contexts,
and have done it at the level of the XML spec - thereby ensuring that
this information would be lost pretty much across the board.

You needn't be interested yourself, nor need you be interested in why
others would care. You just need to be aware that there are times when
throwing away this information causes real irritation, and be prepared
for that.
I'm hoping that future generations of XML APIs will at least preserve
such information if not use it, thereby reducing the amount of conflict
between those who just want the abstractions and those who actually
care what the markup looks like.
At present, those who care about the abstractions and the abstractions
only are far too greatly in the ascendant for me to be comfortable.

I don't find abstraction to be the essence of XML. I find XML to be a
text-based format with labels inside - and I do suspect that foundation
is what makes it popular, not the damn Infoset.
