{ItemId} - Integer ID that represents the item within a list.

{ItemUrl} - URL of the item being acted upon. Only work for documents in libraries. [Not functional in Beta 2]

{ListId} - GUID that represents the list.

{SiteUrl} - URL of the Web site (SPWeb).

<UrlAction Url="javascript:Window.open('http://'+ window.document.location.host +'/BookMarkAdd.aspx?SiteUrl={SiteUrl}&amp;ItemId={ItemId}&amp;ListId={ListId},'','430','543','no');"/>

이런 식으로 사용 하시면 되겠습니다.
