  24       <div class="date">21st February 2017</div>
  25       <div class="body"><p>I just noticed
  26 <a href="http://www.arkivrad.no/aktuelt/riksarkivarens-forskrift-pa-horing">the
  27 new Norwegian proposal for archiving rules in the goverment</a> list
  28 <a href="http://www.ecma-international.org/publications/standards/Ecma-376.htm">ECMA-376</a>
  29 / ISO/IEC 29500 (aka OOXML) as valid formats to put in long term
  30 storage.  Luckily such files will only be accepted based on
  31 pre-approval from the National Archive.  Allowing OOXML files to be
  32 used for long term storage might seem like a good idea as long as we
  33 forget that there are plenty of ways for a "valid" OOXML document to
  34 have content with no defined interpretation in the standard, which
  35 lead to a question and an idea.</p>
  36
  37 <p>Is there any tool to detect if a OOXML document depend on such
  38 undefined behaviour?  It would be useful for the National Archive (and
  39 anyone else interested in verifying that a document is well defined)
  40 to have such tool available when considering to approve the use of
  41 OOXML.  I'm aware of the
  42 <a href="https://github.com/arlm/officeotron/">officeotron OOXML
  43 validator</a>, but do not know how complete it is nor if it will
  44 report use of undefined behaviour.  Are there other similar tools
  45 available?  Please send me an email if you know of any such tool.</p>
