No, they don't. It depends on the MIME type. The spec says application/xhtml+xml pages MUST be parsed with draconian error handling, but pages with text/html need not. Note that text/html is deprecated for XHTML 1.0 but invalid for XHTML 1.1.

In other words, if we use XHTML 1.0 Transitional served with MIME type text/html we shouldn't run into problems.

Of course, we're already scrubbing users' HTML, so I don't see why it would be too difficult to clean it using f.ex the tagsoup algorithm.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
