While using the noop control may be helpful for checking whether an entry could be deleted (or another all-or-nothing operation) it's not helpful to determine which attributes may be modified.
I'm really curious to know what you really want to achieve.
Acl's at attribute-level are unimportant for me. I plan to develop a gui which helps to maintain some entries in an (open)ldap directory. For example, the application should show a delete button if a had "effectiveRights" to delete the specified entry.
