could you clarify the meaning of the keywords "[all]" and "[entry"]
please for attributes. The ID states:

"[all]" means the permission set apply to all attributes of
the entry.

What is the meaning of the above if the scope is subtree?

(EJS) The permission set associated with "[all]"
applies to all attributes of each entry in the
subtree.

What if the permission set comprises n,b and t only?

(EJS) These permissions apply only to entries, not
attributes.  So specification of them in this
context is invalid (we need to update the BNF to
reflect this.


[entry] means the permissions apply to the entire object.

What is the meaning if the scope is subtree?

(EJS) The specified permissions apply to each entry
in the subtree.  Recall that only certain permissions
can be applied to the entire entry (we need to update
the BNF to reflect this).


What if the permission set comprises r, w and o only?

(EJS) These permissions apply only to attributes, so
can only be used with "[all]" or specifically listed
attribute(s).  (we need to update the BNF to reflect
this).

If fact is there any purpose of the keyword [entry] at all given that
we have entry level permissions?

(EJS) It helps focus the permissions to either entry or
attribute quickly and and for clarification and ease of
parsing.
