A stand-alone callback that draws a dotted line over to the right and appends a page number. The info[:params] will be like a standard XML tag with three named parameters:

level:The table of contents level that corresponds to a particular style. In the current TechBook implementation, there are only two levels. Level 1 uses a 16 point font and level1_style; level 2 uses a 12 point font and level2_style.
page:The page number that is to be printed.
xref:The target destination that will be used as a link.

All parameters are required.
