Tim Bray comments on this in the Annotated XML spec (at
http://www.xml.com/axml/axml.html):

Line End Trade-Offs
The idea here is that a programmer need never have to wrestle with the fact
that Windows boxes, Macintoshes, and Unix systems all use different
characters to separate lines. Since XML documents will be stored in files on
all these systems, and will often be broken up into lines, it's absolutely
certain that these documents will use all these different combinations of
carriage-return and line-feed.

But as a programmer using an XML processor, you can count on never seeing
anything but a single line-feed character separating lines. This means your
code will run anywhere.

Since the publication of the spec, we have received a certain number of
complaints from Microsoft Windows programmers, who find it surprising and
disturbing that the data they receive from the XML processor has "weird,
unconventional" line separation. Given the relative number of Windows
programmers, it might have been a good idea to adopt the Windows-standard
CR-LF as the line separator signal, as opposed to the single LF; but it's
too late for that now.

I've noticed myself that my beautifully formatted XML documents do sometimes
have line separators stripped out [from a Windows point of view] when
viewing them in Notepad, but since I only ever need to look at the bare XML
when I'm debugging, it's not really a problem in my case.
