+# XMLParser since the internal ZPT representation uses unicode
+# however the XMLParser (using Expat) can only deal with standard
+# Python strings. However we won't and can't convert directly
+# to UTF-8 within the ZPT wrapper code. 
+# Unicode support for (this issue) should be directly added
+# to zope.tal.xmlparser however this requires a new Zope 3.3.X
+# release. For now we fix it here.
