+/**  
+  @par Protocol Description:
+  The EFI_SERVICE_BINDING_PROTOCOL provides member functions to create and destroy 
+  child handles. A driver is responsible for adding protocols to the child handle 
+  in CreateChild() and removing protocols in DestroyChild(). It is also required 
+  that the CreateChild() function opens the parent protocol BY_CHILD_CONTROLLER 
+  to establish the parent-child relationship, and closes the protocol in DestroyChild().
+  The pseudo code for CreateChild() and DestroyChild() is provided to specify the 
+  required behavior, not to specify the required implementation. Each consumer of 
+  a software protocol is responsible for calling CreateChild() when it requires the 
+  protocol and calling DestroyChild() when it is finished with that protocol.
+
+  @param CreateChild
+  Creates a child handle and installs a protocol.
+
+  @param DestroyChild
+  Destroys a child handle with a protocol installed on it.
