I just exported the stock 'standard_error_message' as XML and
re-imported it successfully in a brand new Zope-2_7-branch instance.

Likewise, my import succeeded in a Zope-2_8-instance, both with the XML
file exported from 2.7 and with one created from 2.8.

My Zope-2_9-branch instance was successfully able to import the XML file
from 2.7, but raises a UnicodeDecode error on the file it produces, as
well as the one created from 2.8. The stack trace here makes it seem as
though Python 2.4.2's expat parser is at fault: it is introducing
non-ASCII characters into the stream where none exist in the source:
- -> r=p.Parse(data)
(Pdb) print [x for x in data if ord(x) > 127]
- -> ("(N)", string_intern(self, name)))
- -> top = end[tag](self, tag, top)
(Pdb) print [type(x) for x in top]
[<type 'unicode'>, <type 'dict'>, <type 'unicode'>, <type 'str'>]
(Pdb) print [x for x in top[-1] if ord(x) > 127]
(Pdb) print [chr(ord(x)) for x in top[-1][10:25]]
['U', '\x03', 'r', 'a', 'w', 'T', '\xcb', '\x04', '\x00', '\x00', '<',
'd', 't', 'm', 'l']
That output seems to me to indicate that the start of the CDATA section
is the problem.

I've just tried again, running with Python 2.4.3c1, because several of
the changelog entries for the release suggest that unicode / encoding /
expat stuff may have been fixed: the decode error is still present.
