In the Microsoft Open XML, you can find at location of last edit:
<w:bookmarkStart w:id="0" w:name="_GoBack"/><w:bookmarkEnd w:id="0"/>
According to http://social.msdn.microsoft.com/Forums/en-US/0e0c5c33-dc4b-4e0f-b795-7868e6a63836/goback-hidden-bookmark-in-open-xml-while-processing-office-2010-word-document?forum=oxmlsdk this is a special bookmark continuously updated when you edit the document.
It allows Shift+F5 (go to previous edit) to work when re-opening a document. It has no meaning for the document itself; it is just a storage for the user's work so far.
Please ignore this one. It continuously introduces new tags per edit.
