 Perhaps we can specify the pool as an attribute, or with a
 rep clause, on the local variable.
+Perhaps a better approach is as follows:
+If a composite type is non-limited, then the accessibility level
+of the declaration of (the ultimate ancestor of) the composite type
+will determine the presumed lifetime of any object of the type.
+This allows objects of the composite type to be freely interassigned
+without having to recheck accessibility.  Any accessibility checks
+are performed when assigning to an access value component of such
+a composite object, presuming the object will ultimately be assigned
+to an object that lives at the same level as the composite type.
+On the other hand, if a composite type is limited, then no composite
+assignments are possible, and each object of the type is created
+in its final resting place, so the accessibility level is known,
+and can be checked when an assignment is performed to an access value

+access values that are components.  See below.
