How does Subversion decide what gets automatically merged?

I'm trying to write some documentation for how to use svn at work,
and have just realized that I don't understand one part of
subversion's algorithms; namely, how does svn decide which files can
be automatically merged, and which can't? E.g., if I'm working on a
text file, and someone else is as well, but in another part of the
file, svn will automatically merge the two without conflicts, but if
I've got a PDF in the repository that gets updated once in a while, a
conflict will be detected even if I and my coworker are editing
totally different parts of the PDF. I'm guessing that this is based
on the MIME type, but I want to be sure.

Thanks,
Cem Karan
