Ok, I didn't realize from the first mail you wrote that the attribut
is not a result of parsing xml but is rather created with
setAttribute.  Your problem is thus not related to serialization but
to insertion.  You cannot use character entities in setAttributes or
other DOM functions. Instead use the corresponding UTF-8 character You
may for example try setAttribute("Attr",chr(123)).
