TYPO3 Core

IE5.5 doesn't support getNamedItem() javascript function.
This function is used to change class name (obj.attributes.getNamedItem("class")) in main module highlighting and dynamic tab menu header generator.

So, all extensions using dynamic tab menu header don't work on IE5.5 (only IE version 6 use this javascript function).

Connect on Typo3 BE with IE5.5
after page loaded, you can see the javascript error
- if you go to workspace module, another error appears.

If we replace this function by getAttribute and setAttribute, now it s working on IE 5.5, 6, and all other allready supported browser.

I made a patch for alt_main.php and template.php. It seems that anothers files use this function.
