Implementation

public static function onBrowseAction( IContextSource $context, array &$facts ) {
        
        // Fetch external data
        $data = ... 
        
        // Check consistency
        if ( $data !== '' ){ 
                $newFacts = array();                    
                
                // 'example-header-info' is being used as key and identifies the 
                // tab title object which should be created as system message
                $newFacts['example-header-info'] = Html::rawElement(
                        'div', array(), $data
                );
                
                // Merge old and new content
                $facts = array_merge ( $newFacts, $facts );
        }
        
        // Always return true in a hook
        return true;
}

&$facts is an array with the key being an identifier for the tabs title (e.g. message text stored for 'example-header-info'). The array value is a string containing formatted information planned to be displayed on the tab.
