Q:

typo3 marking active languages

I want to mark the actual active selected language.
What I want is to give the <a> element a class. Is that possible?
typoscript looks like this:
    ## Localization menu:
temp.langMenu = HMENU
    temp.langMenu.special = language
    temp.langMenu.special.value = 0,3,1
    temp.langMenu.1 = GMENU
    temp.langMenu.1.NO {
    XY = [5.w]+4, [5.h]+4
    transparentColor = #17353e
      backColor = #17353e
    5 = IMAGE
    5.file = fileadmin/bilder/DE-flag-32.png || fileadmin/bilder/US-flag-32.png || fileadmin/bilder/CN-flag-32.png

 }

    temp.langMenu.1.ACT < lib.langMenu.1.NO
    temp.langMenu.1.USERDEF1 < lib.langMenu.1.NO
    temp.langMenu.1.ACT.backColor = #000000

    temp.langMenu.1.USERDEF1 = 1
    temp.langMenu.1.USERDEF1.5.file = fileadmin/bilder/DE-flag-32.png || fileadmin/bilder/US-flag-32.png || fileadmin/bilder/CN-flag-32.png
    temp.langMenu.1.USERDEF1.noLink = 1

A:

ACT < .NO
ACT {
  stdWrap.typolink.ATagParams = class="navLangAct"
}
