[TYPO3-core] RFC: 0002901: API needed to write HTML tags into the FE header tags directly

Hello Dmitry,

thanks for looking on this.

        global $TSFE, $GLOBALS;
...
        $GLOBALS['TSFE']['tx_ttproducts-js'] = $code;

Gives the error message:
Fatal error: /Cannot use object of type tslib_fe as array/ in

However
$GLOBALS['TSFE']->additionalHeaderData['tx_ttproducts-js'] = $code;
works.

I have never seen something like this before and cannot find it
documented anywhere.

Well, maybe there are even other extension programmers who did not know
and read about your solution to this.

Yes, a solution to this would be fine.
