title: Error XML Not Well Formed - Sigil XHTML created from notepad++
body: <p>I am quite new to the epub world.</p>
  
  <p>I converted my word doc to xhtml using notepad++. I am now trying to clean up the code and use the flightcrew plugin in sigil.</p>
  
  <p>I keep getting this error</p>
  
  <blockquote>
    <p>Error XML not well formed : attribute name expected near column 11</p>
  </blockquote>
  
  <p>Am I missing something obvious? I can't see anything wrong. I've tried deleting the dc:dc: double up but it only creates more errors</p>
