The `ElementInstancer` is a more advanced item, and the documentation resides in here rather than the [wiki:documentation/LuaManual/APIReference] because of a "private" usability item that conflicts with the documentation on the other page.

ElementInstancers are supposed to instance Elements as their name implies. But, according to the API documentation, Element does not have a constructor.

The documentation lied. Element has a constructor, and it looks and acts the same as every other type that has one. There is no other type that has a "hidden" constructor.

 `Element `'''new'''(`string` ''tag'')::
   Creates a new ''Element'' for use in Lua. It is reference counted and tagged to be able to be garbage collected, so make sure to keep a reference of this ''Element'' around until you do not need it anymore, otherwise it will be released.

__Do not ever call the Element constructor outside of an ElementInstancer.__ If you do, there will be memory leaks and errors.

Abstract class ElementInstancer. Get one from C++ by calling ElementInstancer.new, and register it as a tag name by calling rocket.RegisterTag. Make sure to set the InstanceElement property to an appropriate Lua function.

 `ElementInstancer `'''new'''()::
   Creates a new ElementInstancer for use in Lua. To put it to use, call ''rocket.RegisterTag'' with this object as the second argument. 

 '''InstanceElement'''`   `=function(`string` ''tag'') return `Element` end::
   The __only__ appropriate place to use the ''Element.new'' function.
