+  The PAL Library provides a service to make a PAL CALL.  This service is identical\r
+  in functionality to AsmPalCall() in the functions of the Base Library specific to Intel Itanium architecture.\r
+  The only difference is that the PAL Entry Point is not passed in.  Implementations\r
+  of this library class must manage PAL Entry Point on their own.  For example, a PEI\r
+  implementation can use a PPI to lookup the PAL Entry Point, and a DXE implementation\r
+  can contain a constructor to look up the PAL Entry Point from a HOB.  This library class\r
+  is only available on Intel Itanium-based platforms.\r
