[Zope] zopeXMLMethods and zope 2.8.x

[Kees de Brabander]

I succeeded using zopeXMLMethods up to zope 2.7.8 after adapting its
__init__.py (see
http://mail.zope.org/pipermail/zope/2005-February/156670.html by Anton
Stonor), which was necessary starting with zope 2.7.3. Trying to use this
very same zopeXMLMethods product (that is with adapted __ini__.py) in zope
2.8.4, however, resulted in exactly the same error I got with the original
__init__.py in zope 2.7.8 (traceback below)???
Does anybody have a solution?

Trying to add a xsltmethod in the zmi brings the authentication dialog up
and results in an unauthorized error:
