 It looks like we're talking about two different things here.

 The suggested patch just changed the generated xml from
 <b class_id="1" class_name="B<int>" ...>
 <b class_id="1" class_name="B&lt;int&gt;" ...>

 I'm not sure, if class_name="B<int>" is valid XML, but i think so. At
 least it is unambiguous, because the angle brackets are enclosed by
 quotation marks. So, at a closer look, the xml-parser may be the real
 cause of the problem and my patch is more the workaround for this.

 The case you are describing above doesn't come from using
 "BOOST_CLASS_EXPORT ( B<int> )", but from "ar &
 BOOST_SERIALIZATION_BASE_OBJECT_NVP( B<int> )". I added it to my testcase
 and at a quick view, that also seems to work for other archive types like
 text_archive, but fails for xml_archives. But for that case, the
 xml_oarchive fails, not the iarchive. So it is recognized when writing the
 serialization, and not until reading it.

 I'd like to find a solution here. In the best case, the xml-reader is
 fixed to read class_name="B<int>", IF that is valid xml.
 But at least, the xml_oarchive should not be able to create archives, that
 can't be read by the xml_iarchive.
