[TYPO3-english] Cache HTML comments

> No idea about TDS unfortunately.

I've found the place in core where these comments are defined  
(class.tslib_pagegen.php):

$GLOBALS['TSFE']->additionalHeaderData =
array ('<!--HD_' . $GLOBALS['TSFE']->config['INTincScript_ext']['divKey']  
. '-->'); // Clearing the array

$GLOBALS['TSFE']->additionalFooterData =
array ('<!--FD_' . $GLOBALS['TSFE']->config['INTincScript_ext']['divKey']  
. '-->'); // Clearing the array

$GLOBALS['TSFE']->divSection .=
'<!--TDS_' . $GLOBALS['TSFE']->config['INTincScript_ext']['divKey'] .  
'-->';

No idea what a divSection is - but my question is now completely answered.
Thanks again! :)
