If you want people to post it to mailing lists, the patch format has to be
human browsable. This:
<text-delta
id="3">U1ZOAAAAHQQZlkQOg1RoaXMgaXMgYWRkZWQgZmlsZSBuZXcxLgo=
</text-delta>
is not human-intelligible, even if it is "plain text".
But the properties diffs are reasonable; if the XML diff were extended to
support a <diff-delta> element (as a human-readable 'diff -u' format
alternative to <text-delta>) you might end up with a patch format which is
*both* gnu-patch *and* svn-friendly: patch will ignore lines it doesn't
understand, while svn would be able to use those extra lines to encode
property information.
I propose 'svn xdiff' to generate this output.
