How about this format for "blame --xml" (non-XML shown first)? (Apologies for
starting with the unrequested "blame --xml" - it just came first in the
alphabet and seemed easiest too.)

~/src/subversion> svn blame ~/tmp/sandbox/t -v -r40:HEAD
      - - - hello -
committed in r17
      - - - bye - committed
in r32
      - - - Third line -
committed in r33

~/src/subversion> svn blame ~/tmp/sandbox/t --xml -v -r40:HEAD
<?xml version="1.0" encoding="utf-8"?>
<text>hello - committed in r17</text>
<text>bye - committed in r32</text>
<text>Third line - committed in r33</text>

(Without "-v", the "date" elements are omitted, just like in the non-XML case.)

A thought that won't go away is that "blame" really ought to return just the
revision number for each line; the author, date, and any other
revision-specific info - and even the line of text from the file - can be
looked up separately. But I don't think that would be the most useful and
convenient thing to do. Perhaps, though, the XML ought to contain a main
section with just rev numbers and another (log-like) section that maps rev
numbers to author, date, etc. My thoughts lie just on the side of that being
an abstraction which would be suitable for a programming interface, whereas
"--xml" really just needs to give a simple XML wrapping of the normal text
output. Your thoughts?
