svn info --xml malformed XML on error

[Steven R. Loomis]

svn info --xml gives malformed XML on error.. could it detect this 
situation and still cleanup the XML, or not output any XML at all?  
svnversion by comparison outputs 'exported'.

-s
$ svn info --xml /tmp
<?xml version="1.0" encoding="UTF-8"?>
<info>
svn: E155007: '/tmp' is not a working copy
$ svn --version
