+ * Service Access Point (SAP)
+ *
+ * A SAP specifies the definition of an interface used between two adjacent
+ * layers.  The SAP is named for the services the lower layer provides to 
+ * the upper layer.
+ *
+ * The types of SAPs used are:
+ * 	Stack - defines the interfaces between stack service entities.
+ *		These are further divided into:
+ *
+ *		Stack class SAP - which identifies the type of interface
+ *			used.  All SAPs of a particular class will provide
+ *			the same interface services to the higher layer.
+ *			All stack command codes are constructed using class
+ *			SAP values.
+ *
+ *		Stack instance SAP - which identifies the specific identity
+ *			of the layer providing the class interface.
