Quick xml help

Im loading an external menu using xml…

<item name=“video” action=“video” variables=“video/defaultvideo.flv”/>

That works…

Now If i wanted to add a variable to have copy with the video. How do i do that? Whats the proper xml syntax?

is it?

<item name=“video” action=“video” variables=“video/defaultvideo.flv” copy=“This is a cool video.”/>

Thanks.
