   <choice> may optionally contain a 'relatedvalue' attribute, which
   if present will cause a text entry to appear to the right of the
   selection.  The value of the relatedvalue attribute is a variable
   into which the text entry will be stored e.g.:
   <choice computer='numberprovided" relatedvalue="num">Type the number in:</choice>
   
   <choice> may contain a relatededefault atribute which, if the
   relatedvalue attribute is present will be the initial value of the input
   box.
