Deltas and unordered files

I'm just curious if anyone knows how well Subversion handles unordered
files (eg. XML files where the order of 'records' is unimportant, and
tend to be written out in fairly random fashion, meaning that every time
the file is modified & committed the diff consists of nearly every line
in weird patterns).

I'm specifically thinking of Visual Studio's .resx files at the moment;
I suspect that VS loads them into a hashtable (randomising their order)
and then writes them back out, leading to large diffs.

Will this result in the entire file contents (or more, with bookkeeping
overhead) being duplicated for each revision it's changed in? Or is it
smarter than that?
