svntest parsing output of `svn proplist --verbose`
Currently svntest parses the output of `svn proplist --verbose` to
retrieve the list of properties for an item. When the output format
of this command changed between 1.5 and 1.6, svntest was updated to
understand the new format (but only the new format). As a result you
need matched versions of svn and svntest in order for it to function
correctly. It is not forward or backward compatible.
This is apparently not a problem for development of Subversion but
cvs2svn pulls in svntest as an external and uses it with whatever
version of svn that the user currently has installed. Things break
when the user doesn't have the expected version installed.
It would be nice if svntest would be able to query properties
successfully even when run with 1.5. Writing a parser that
understands both text formats seems difficult but there's the '--xml'
option to output in XML format and it seems made for just this
situation. Is there something precluding the use of the XML format
for svntest?

I didn't even think python3.1 was *a* version we support, let alone exhaustive.

Apparently yes:
$ python3.1 -c 'from xml.dom.minidom import parseString'

prop_tests.py covers most of 'svn proplist', except ... 'svn proplist --xml'.

The test suite already tests the output of 'svn diff --summarize
--xml' in svntest/actions.py using expat, so we're ok for python 2.4
<= version < 3.0.

The Python versions we support ship with an XML parser, right?

Nor do I, just as long as we make sure to still test the "standard"
output somewhere in the testsuite.

I don't think there is anything precluding the use of "svn proplist
--xml" for svntest's property-checking functions.
