Syntax
            
            sp_create_secure_feature_key ( 
    name, 
    auth_key, 
    features )
         
Parameters
            
            - name – the VARCHAR (128) name for the new secure feature key. This
                        argument cannot be NULL or an empty string.
 - auth_key – the CHAR (128) authorization key for the secure feature key.
                        The authorization key must be a non-empty string of at least six
                        characters.
 - features – the LONG VARCHAR comma-separated list of secure features
                        that the new key can enable. Specifying "-" before a feature means that the
                        feature is not re-enabled when the secure feature key is set.
