  A hook-in library for MdeModulePkg/Universal/Acpi/AcpiTableDxe.\r
\r
  Plugging this library instance into AcpiTableDxe makes\r
  EFI_ACPI_TABLE_PROTOCOL and (if enabled) EFI_ACPI_SDT_PROTOCOL depend on the\r
  platform's dynamic decision whether to expose an ACPI-based hardware\r
  description to the operating system.\r
\r
  Universal and platform specific DXE drivers that produce ACPI tables depend\r
  on EFI_ACPI_TABLE_PROTOCOL / EFI_ACPI_SDT_PROTOCOL in turn.\r
