/** @file
  A hook-in library for MdeModulePkg/Universal/Acpi/AcpiTableDxe.

  Plugging this library instance into AcpiTableDxe makes
  EFI_ACPI_TABLE_PROTOCOL and (if enabled) EFI_ACPI_SDT_PROTOCOL depend on the
  platform's dynamic decision whether to expose an ACPI-based hardware
  description to the operating system.

  Universal and platform specific DXE drivers that produce ACPI tables depend
  on EFI_ACPI_TABLE_PROTOCOL / EFI_ACPI_SDT_PROTOCOL in turn.
