I think you meant to say: You can plug in any diff algorithm you want
into the source code, as long as it generates the internal svndiff
format in the end, which is very non-pluggable ;)

In fact, you *could* plug in your xmldiff, though it would likely be
pointless, since you'd have to take the results and turn it into
byte-oriented insert + copy instructions, which svndiff uses.
