Objects (like features, domains etc) managed by the Application Server demand specific permissions to be accessed (i.e. read, modified, etc). Each privilege grants exactly one permission to one specific privilege subject on one specific privilege object. Each privilege object type has its own set of permissions that can be granted.
Besides its name each permission has a number. This should help you identifying the right permission if you are reading this Reference Manual but your Application Server Language or Client language is not set to English.
