Not exactly original but fabulous! I'm suprised you haven't fixed that oversight yet. (PS the VITs could use the same upgrades the examples and Template Projects got! perhaps even a cross link to a "where you might use this vit or xxt" and definately a "Concepts used" link)
Now lets add the side benefit. When created from "New..." the xxT contains not only base documentation but the template becomes part of the FQN. Object Name of Type of object Template in Library on Target in Project. VERY powerful!
