+  This library does not contain any functions or macros.  It simply exports a global\r
+  pointer to the DXE Services Table as defined in the Platform Initialization Driver\r
+  Execution Environment Core Interface Specification.  The library constructor must\r
+  initialize this global pointer to the DX Services Table, so it is available at the\r
+  module's entry point.  Since there is overhead in looking up the pointer to the DXE\r
+  Services Table, only those modules that actually require access to the DXE Services\r
+  Table should use this library.  This will typically be DXE Drivers that require GCD\r
+  or Dispatcher services.\r
