#12438: Wrong additional closing tag in boost::archive::xml_woarchive
------------------------------+---------------------------
 Reporter:  anonymous         |      Owner:  ramey
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  serialization
  Version:  Boost 1.62.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------------
 boost::archive::xml_woarchive writes an additional line
 '''</boost_serialization>'''
 after the closing tag
 '''</boost_serialization>'''
 The output of boost::archive::xml_oarchive is correct.

 The ouput of xml_woarchive is
 {{{
 <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
 <!DOCTYPE boost_serialization>
 <boost_serialization signature="serialization::archive" version="14">
 <w_foo class_id="0" tracking_level="0" version="0"></w_foo>
 </boost_serialization>
 &lt;/boost_serialization&gt;
 }}}

 The source code is
