  70.     SUMMARY:
  71.      following parameter triggers a (quite time consuming) workaround for enabling of chapter links in the table-of-content.
  72.  
  73.     IN DETAIL:
  74.      Currently some links used in the Office XML (for example, in the content table as '#7.Some%20Example%20Headline%7Outline')
  75.      are not a valid URLs (cp. bug id# 102311).
  76.      No file destination is specified nor exist any anchor element for these links in the Office XML.
  77.      A workaround for this transformation therefore had to be made. This time-consuming mechanism is disabled by default and
  78.      can be activated by a parameter (i.e. 'childDocumentExist'). A creation of an anchor is made for each header element.
  79.      All header titles gonna be encoded to be usable in a relative URL.  -->

  83.         CREATION OF A HELPER VARIABLE AS WORKAROUND FOR THE CONTENT TABLE ULR BUG
  84.  
  85.  
  86.         As no valid URL from the content table to the child documents exist in the content table,
  87.         a work-around is done:
  88.  
  89.         First two helper variables are being created.
  90.  
  91.         One containing the list of all references of the master document:
  92.         containg all their title,
  93.         for example:
  94.  
  95.             <chapter-ref title="aTitle 1" />
  96.             <chapter-ref title="aTitle 2" />
  97.             <chapter-ref title="aTitle 2/>
  98.             <chapter-ref title="aTitle 3/>
  99.  
  100.         The other containing all heading from the child documents linked from the master document.
  101.         The variable 'childrenHeadings' contains their title and the number of preceding similar titles,
  102.         for example:
  103.  
  104.  
  105.             <child file-url="aURL">
  106.                 <heading title="aTitle1" level="1">
  107.                 <heading title="aTitle2" level="2">
  108.                 <heading title="aTitle3" level="1">
  109.             </child>
  110.  
  111.         For each chapter reference from the content table the
  112.  
  113.          by encoding the chapter names of the child document with the java URLEncoder and
  114.         use this as a part of a link. Furthermore for all heading elements a encoded anchor will be created from the heading.
  115.         Last the workaround parses all children documents for this anhor, as there is no distinction of files from the content table entries.
  116.  
  117.         The new added node set to the globalData variable concering the content table is written as
  118.  
  119.  
  120.         <content-table-headings>
  121.             <heading file-url="aFileURLToTheGeneratedHeading1" level="1">
  122.             <heading file-url="aFileURLToTheGeneratedHeading2" level="2">
  123.             <heading file-url="aFileURLToTheGeneratedHeading1" level="1">
  124.             <heading file-url="aFileURLToTheGeneratedHeading2" level="2">
  125.         </content-table-headings>
  126.  
  127.  
  128.         Preconditions:
  129.         The correct sequence of child documents according to the Content Table is necessary, granted by the office.
