 |`_Create_lock_level_(name)`|A statement that declares the symbol `name` to be a lock level so that it may be used in the annotations `_Has_Lock_level_` and `_Lock_level_order_`.|
 |`_Has_lock_kind_(kind)`|Annotates any object to refine the type information of a resource object. Sometimes a common type is used for different kinds of resources and the overloaded type is not sufficient to distinguish the semantic requirements among various resources. Here's a list of pre-defined `kind` parameters:<br /><br /> `_Lock_kind_mutex_`<br /> Lock kind ID for mutexes.<br /><br /> `_Lock_kind_event_`<br /> Lock kind ID for events.<br /><br /> `_Lock_kind_semaphore_`<br /> Lock kind ID for semaphores.<br /><br /> `_Lock_kind_spin_lock_`<br /> Lock kind ID for spin locks.<br /><br /> `_Lock_kind_critical_section_`<br /> Lock kind ID for critical sections.|
 |`_Has_lock_level_(name)`|Annotates a lock object and gives it the lock level of `name`.|
-|`_Lock_level_order_(name1, name2)`|A statement that gives the lock ordering between `name1` and `name2`.|
+|`_Lock_level_order_(name1, name2)`|A statement that gives the lock ordering between `name1` and `name2`.  Locks that have level `name1` must be acquired before locks that have level `name2`|
 |`_Post_same_lock_(expr1, expr2)`|Annotates a function and indicates that in post state the two locks, `expr1` and `expr2`, are treated as if they are the same lock object.|
 |`_Releases_exclusive_lock_(expr)`|Annotates a function and indicates that in post state the function decrements by one the exclusive lock count of the lock object that's named by `expr`.|
 |`_Releases_lock_(expr)`|Annotates a function and indicates that in post state the function decrements by one the lock count of the lock object that's named by `expr`.|
