управление заголовками в ждумле

просматриваю исходный код страниц. так понимаю присутствуем куча мусора, например :

<h2>Your are currently browsing this site with Internet Explorer 6 (IE6).</h2>

<h3>Your current web browser must be updated to version 7 of Internet Explorer (IE7) to take advantage of all of template's capabilities. </h3>

<b>Why should I upgrade to Internet Explorer 7?</b> Microsoft has redesigned Internet Explorer from the ground up, with better security, new capabilities, and a whole new interface. Many changes resulted from the feedback of millions of users who tested prerelease versions of the new browser.

The most compelling reason to upgrade is the improved security. The Internet of today is not the Internet of five years ago. There are dangers that simply didn't exist back in 2001, when Internet Explorer 6 was released to the world. Internet Explorer 7 makes surfing the web fundamentally safer by offering greater protection against viruses, spyware, and other online risks.
