Валидатор w3.org ругается на дефольный шаблон

      Warning Line 629, Column 52: NET-enabling start-tag requires SHORTTAG YES
            <p><span style="font-size: large;"><br />
 
For the current document, the validator interprets strings like <FOO /> according to legacy rules that break the expectations of most authors and thus cause confusing warnings and error messages from the validator. This interpretation is triggered by HTML 4 documents or other SGML-based HTML documents. To avoid the messages, simply remove the "/" character in such contexts. NB: If you expect <FOO /> to be interpreted as an XML-compatible "self-closing" tag, then you need to use XHTML or HTML5.
 
This warning and related errors may also be caused by an unquoted attribute value containing one or more "/". Example: <a href=http://w3c.org>W3C</a>. In such cases, the solution is to put quotation marks around the value.
