+  @param keyuse  Evaluated KEYUSE structure    
+
+  @details
+  This function is supposed to be used after the best execution plan have been
+  already chosen and the JOIN_TAB array for the best join order been already set.
+  For a given KEYUSE to access this JOIN_TAB in the best execution plan the
+  function checks whether it really can be used. The function first performs
+  the check with access_from_tables_is_allowed(). If it succeeds it checks
+  whether the keyuse->val does not use some fields of a materialized semijoin
+  nest that cannot be used to build keys to access outer tables.
+  Such KEYUSEs exists for the query like this:
+    select * from ot 
+    where ot.c in (select it1.c from it1, it2 where it1.c=f(it2.c))
+  Here we have two KEYUSEs to access table ot: with val=it1.c and val=f(it2.c).
+  However if the subquery was materialized the second KEYUSE cannot be employed
+  to access ot.
+
+  @retval true  the given keyuse can be used for ref access of this JOIN_TAB 
+  @retval false otherwise
