title: Why a Word file duplicated with python-docx has different XML than the original
body: <p>I'm generating .docx files from Word documents that have changed Fonts but maintain the same format, style and information content. All has been done via the python-docx API.</p>
  
  <p>There are still working-arounds not within the scope of the API (such as duplicating numeric bullets from source and inserting non-strings into Headers/Footers). I'm approaching these via lxml.</p>
  
  <p>The XML of the original file and the generated file, while similar, are not identical irrespective of the lack of <code>&lt;w:numPr&gt;</code> tags.  Why is that? The output .docx files look as expected.</p>
  
  <p>This complicates working with low level lxml fixes.</p>
