[TYPO3-english] How to get a <!-- ..--> in the header

[Philipp Holdener]

Hello

How can I get something like this in the header?

<!-- TradeDoubler site verification 1111111 -->


I try this code

page.headerData.5 = HTML
page.headerData.5.value (
        <!-- TradeDoubler site verification 1111111 -->	
)

--> no effect in the frontend!

Thanks for help

Greetings
Philipp
