The link title attribute can only contain plain text. 

If what you call the "page summary" is a PageTextVariable, you cannot be sure 
that someone didn't add styles, links, tables or other content that is not 
allowed in link title attributes.

This code will place the plain text of the PageTextVariable in the tooltip 
title of the link:

  $FmtPV['$Summary'] = 'Keep(str_replace(array(\'"\',"\'"),
    array(\'"\',\''\'),PageVar($pn, "\$:Summary")))';
  $LinkPageExistsFmt = "<a class='wikilink' title='{\$Summary}'
