I have an attribute that have to be unique (but i need also to write it myself) , so i would like to be able to create it the first time, and if i try to create it again, i want not be able.
Is there a way to do that ?


That kind of functionality is unfortunately not implemented. All you can do is to use an automatically generated unique attribute with the syntax:
Preset <attribute> = XYZ-####

or similar. Please consult the documentation for details.
