/**
 * To see what parts comprise your docx, try the PartsList sample.
 * 
 * There will always be a MainDocumentPart, usually called document.xml.
 * This sample shows you what objects are in that part.
 * 
 * It also shows a general approach for traversing the JAXB object tree in
 * the Main Document part.  It can also be applied to headers, footers etc. 
 * 
 * It is an alternative to XSLT, and doesn't require marshalling/unmarshalling.
 * 
 * If many cases, the method getJAXBNodesViaXPath would be more convenient,
 * but there are 3 JAXB bugs which detract from that (see Getting Started).  
 * 
 * See related classes SingleTraversalUtilVisitorCallback 
 * and CompoundTraversalUtilVisitorCallback
