+* Define and maintain a set of attribute definitions that are relevant for a reasonably broad portion of the PHP ecosystem so that different tools and users can use and rely upon a defined set of attributes with less duplication.
 * Provide one or multiple composer-installable packages containing 
   the code for the attributes in the registry
 * provide methods to maintain the registry and add, modify and remove attributes from it
