I don't know what document you're citing here.  This is not from
either the Namespaces in XML specification:

    http://www.w3.org/TR/1999/REC-xml-names-19990114/

or the Namespaces in XML 1.1 specification:

    http://www.w3.org/TR/2004/REC-xml-names11-20040204/

I'll note that the XML parser used in Zope implements the first
specification, which clearly states that a qualified name can contain
at most one colon, so any attribute containing more than one colon
should not have namespace processing applied.
