/**
 * This simple example demonstrates 
 * populating content controls with values
 * obtained from a Custom XML file in
 * the docx.
 * 
 * There will only be something to do
 * if the content in the XML part
 * is different from the content 
 * in the content control pointing to it.
 * 
 * Word does this itself automatically (its
 * a 2 way association, so if the user edits
 * the document in Word, Word updates the XML part), but if you
 * have a Word document containing content controls,
 * this sample demonstrates how you could
 * populate those programmatically.  You might
 * then use docx4j to generate a pdf or an html.
 * 
 * In the real world, you are likely to
 * want to change the data.  For how to do that,
 * see:
 * - ContentControlsXmlEdit
 * - https://github.com/plutext/OpenDoPE-WAR/blob/master/webapp-simple/src/main/java/org/opendope/webapp/SubmitBoth.java
 * 
 * You're also likely to want to 'repeat' data,
 * and conditionally exclude paragraphs.  See 
 * ContentControlBindingExtensions for more on that.
