-== <tt>setprop()</tt> functionality ==
-<tt>setprop()</tt> concatenates a list of input arguments by means of inserting a "/" in between. That is nice for properties, as this slash is part of the tree. However, when one wants to make use of indices, like [0], one has to concatenate by hand (using "~") ''inside'' one part of the string argument list. An example is:
-  var i = 4;
-  setprop("instrumentation","cdu","page["~i~"]","title","MENU");
-This results in <code>instrumentation/cdu/page[4]/title = 'MENU' (string)</code>.
