title: How many headerX.xml files can there be contained in a .docx file?
body: <p>I've set up some templating functionality which modifies existing .docx files to insert custom values.</p>
  
  <p>It worked for a while with the values I was interested in being contained within the files <strong>word/header1.xml</strong> and <strong>word/header2.xml</strong></p>
  
  <p>Now the code has stopped working and the values seem to be in <strong>word/header3.xml</strong></p>
  
  <p><strong>How many headerX.xml files can there be, where X is a number?</strong> I don't know whether to alter my code to allow for an unlimited number (which is more of a pain) or whether there can be only, say, 5, or one per page, or some other limit. </p>
