(I looked through the html-ig/wg/whatever archives and saw no
post about this, so excuse me if this has been pointed out)
According to the HTML 2.0 DTD (level 1) (BTW, the hyperlink labeled
"Current level 2 DTD" at
<URL:http://www.hal.com/users/connolly/html-spec/notes/ReviewTopics.html>
point to html-1.dtd), nested character formatting elements are
allowed. For example, the following is currently legal:
<em>Hello <em>There</em></em>
Does this really make sense.
Here's a diff of the proposed rule changes:
