[TYPO3-dev] Removing strip_tags dangerous?

[Georg Ringer]

Hello,

for my current extension project I would like to have html-tags inside 
the alt/title tag of an image. These are removed in 
class.tslib_content.php > function getAltParam().

----
$altParam = ' alt="'.htmlspecialchars(strip_tags($altText)).'"';
----

Is it dangerous to remove the strip_tags function?

thanks a lot
Georg
