+  @par Protocol Description:
+  Typically, protocol interface structures are identified by associating them with a GUID. Each
+  instance of a protocol with a given GUID must have the same interface structure. While all instances
+  of the GUIDed Section Extraction Protocol must have the same interface structure, they do not all
+  have the same GUID. The GUID that is associated with an instance of the GUIDed Section
+  Extraction Protocol is used to correlate it with the GUIDed section type that it is intended to process.
