Another approach...

You can remove the tab and replace it with a tab of your own content from the Product object like this:

abstract class DefineTabShowSpecification extends \XLite\View\Product\Details\Customer\Page\APage implements \XLite\Base\IDecorator
{


    protected function defineTabs()
    {
        $list = parent::defineTabs();
		unset($list['Specification']); //remove default X-cart specification
		
		$tmp = $this->getSpec(); 
   		if (!empty($tmp)) {  //if the spec field has data...
        	$list['Specification'] = array(
        	    'list' => 'product.details.page.tab.detailed_spec', //... show it in the specification tab
        	);
    	} 

        return $list;
    }
	
    protected function getSpec(){
		return $this->getProduct()->specification;	
	}
		
} 

(also need in skins/default/en/module/DEV-ID/MODULE-NAME/ folder

{**
 * Product details spec tab 
 *
 *
 * @ListChild(list="product.details.page.tab.detailed_spec")
 *}

{product.specification:h}

)


In this case the client wants to add text and images into the Specification tab. I'd previously added this to the Product Info section in admin so product_translations in the database contains a specification column. The code above display the data from this column.
