 These are optional sections that describes the FMP payload content for FMP
 Capsule files.
 
+There must be at least one and at most two `<FmpFileData>` statements.  The
+`<FmpFileData>` statements start with `FILE DATA`.  The first <FmpFileData>
+statement provides the information for UpdateImage in an
+`EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER`.  The second <FmpFileData>
+statement, if present, provides the information for VendorCode in an
