                     Usage:
                         On the standard value (or the actual item) there is a "Fallback Fields" field within a "Fallback" section.
+                        This is a single line text field that may be formatted as a Name/Value pair or XML.
                         Configure the 'name' part with the name of the field that should have fallback
                         Configure the 'value' part with the '|' separated list of fields it should check for a value
+
+                        Name/Value pair - Name=Value1|Value2&Name2=Value3
+
+                        XML -
+                          <fallback>
+                            <setting target="{id}" source="{id}|{id}|{id}..." enableEllipsis="true|false" clipAt="{number chars}" />
+                            <setting target="{id}" source="{id}|{id}|{id}..." enableEllipsis="true|false" clipAt="{number chars}" />
+                              ...
+                          </fallback>                        
+
+                  EnableNestedFallback - In certain scenarios a field may be configured with multiple fallback processors. 
+                                              For instance, AncestorFallback. Should the Ancestor value be determined before translation happens?
