Pages are rendered with deprecated HTML tags, such as <b> rather than <em>. This is the case for me on en.wp; user agent string: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4
<b> is not deprecated in XHTML, and <em> is not equivalent. <b> marks bold specifically, <em> marks emphasis generally, and <strong> marks stronger emphasis generally. If it were changed, <strong> would be the closest equivalent.
Of course, you are correct, <b> was superseded by <strong>, while <em> is the equivalent of <i>. Looking at the page again, I can see that it is valid XHTML. Whoops.
