I would like to create an empty node in Maya (mel language), in which I can store my attributes (visible to the end-user).
The reason why I would need an empty node, is because I don't need any locator information or additional standard Maya information, just a couple of my custom attributes. to be visibl in the node.
createNode "<What_type_should_I_put_here?>" -n "MyCustomEmptyNode";
