I don't believe there would be any way to arbitrarily bold certain nodes unless you were to include a script (like jquery) that you could use to get the specific DOM elements that you want to modify and add a class to them that you could specify as bold in your stylesheet. That's one possibility. Of course, if you modify the site map page, you would need to go back and replace that script tag each time you update your code from SVN. Otherwise you could copy and rename the sitemap page, customize it, and just use your custom page. If you just made your own custom page, you could then modify the code-behind and use databinding methods to find and bold the nodes you want. That might even be easier.
