I've said this a few times already, but I'll say it again. I'm not
really a programmer. I have written simple BASIC programs in the past.
I've dabbled with machine/assembly language on 6800, 6502, and 8086
compatible microprocessors. More recently, I have written a couple
very simple C language programs. When I look at typical source code
written in C/C++, Perl, or Java, I usually don't a clue what is going
on. These syntax systems seem very alien to me, and nearly
indecipherable. The examples of XML I have seen, are very readable by
comparison.
I think this says a lot. If a non-programmer like me can more easily
interpret XML than the common computer languages in use, it *has* to
be considered human-readable. You claim the word "barely" comes to
mind, but perhaps this is because you have grown so accustomed to
reading another existing computer language. XML *does* look different
than C/C++, Java, etc. You simply have to forget all your
preconceptions of what a language "should look like" to be able to
judge it properly.

Perhaps you are forgetting that several people have wanted to write a
robust parser for POV in the past, and to my knowledge, no one has.
Apparently, having the POV parser source code available isn't enough
help.

I guess it must depend on the human in question. :)

Nigel has already given you a list of advantages. They seemed like
perfectly reasonable and understandable concepts to me. I had also
given some potential advantages myself (Keep in mind, my vision of an
XML implementation was different than Nigel's. I must admit that his
vision of an XML implementation is more interesting.)
