Just a thought: you /could/ also do this without additional markup,
provided that you treat all 2 letter groups as languages.

SDV($LinkLanguageFmt,"<div class='language'><a class='languagelink' href='\$LinkUrl'>\$LinkText</a></div>");
Markup('[[lang','<[[','/\\[\\[(([[:upper:]][[:lower:]])[\\/.]][^\\|\\]]+)\\]\\]/e',
  "Keep(MakeLink(\$pagename,PSS('$1'),PSS('$2'),'',\$GLOBALS['LinkLanguageFmt']),'L')");

Then any links of the form [[Aa.text]] will treat Aa as the link text.

If not now, the approach may come in useful one day...
