Typo3 adds tt_content record id to header text

Question

I'm working with Typo3 v6.1 and when I add standard header block to the page, the block's id is being added to header's text body. Here are some screenshots:

here is backend setting

and here is corresponding fron-end result, note the element id 324, which is added to the wrapper tag and to the tag content

I'm trying to get rid of the id in the content. Id as attribute is desired and added by my TypoScript code

lib.stdheader.stdWrap.dataWrap.override = <header ... id="c{field:uid}">|</header>

But I have no idea who and where inserts the id to the content. I'm currently looking at /typo3/sysext/css_styled_content/static/v6.0/setup.txt and trying to override some blocks of configuration related to headers, like lib.stdheader or tt_content.header, but whatever wrapper setting I change, my change only affects the "outer" html code, i.e. this added id is always inside that wrappers :(

Can someone help me spotting the appropriate rendering config or rendering function to debug it?

Answer 1

Go to the page where this occurs in the Web > Template module. Then select "TypoScript Object Browser" from the top menu.

Open the path "lib.stdheader".

Your problem must be within lib.stdheader.10 and lib.stdheader.20. Inspect these elements - you will see all configuration applied to it.
