[Typo3] overwriting stdWrap in sr_language_menu

[Jane Larsen]

I'm trying to change the CSS class for my language menu:

temp.languagemenu < plugin.tx_srlanguagemenu_pi1
temp.languagemenu.flag.CUR.stdWrap = <div class="TEST"><img 
src="{$plugin.tx_srlanguagemenu_pi1.pointerImage}" style="width:7px; 
height:10px;" /> | </div>

But it still gets the standard "CUR" class instead of my TEST class...

Is this just because I missed some notation or something else?

(I've been looking at this page:
