[TYPO3-mvc] How to remove Parsetime info tag for AJAX

[g4-lisz at tonarchiv.ch]

Hi there

Since 6.2 I get a JS errors because the JSON answer from my servers
conatins a <!-- Parsetime: 178ms --> tag at the end of data.

The setup for my document type looks like this:

tmp.ajaxConf = PAGE
tmp.ajaxConf {
  typeNum = 1249058000
  config {
    disableAllHeaderCode = 1
    xhtml_cleaning = 0
    admPanel = 0
  }
}
my_plugin < tmp.ajaxConf
my_plugin {
  typeNum = 1371393670
  10 < tt_content.list.20.my_plugin
}

Is there a now config variable for this type of output?

Cheers,
Till
