+# Instance of PCD Library using PCD Protocol.
+#
+# There are two PCD protocols as follows:
+# 1) PCD_PROTOCOL
+# It is EDKII implementation which support Dynamic/DynamicEx Pcds.
+# 2) EFI_PCD_PROTOCOL
+# It is defined by PI specification 1.2, Vol 3 which only support dynamicEx
+# type Pcd.
+#
+# For dynamicEx type PCD, it is compatible between PCD_PROTOCOL and EFI_PCD_PROTOCOL.
+#
+# This library instance uses the PCD_PROTOCOL to handle dynamic PCD request and use
+# EFI_PCD_PROTOCOL to handle dynamicEx type PCD.
+#
+# Note: A driver of type DXE_RUNTIME_DRIVER and DXE_SMM_DRIVER can only use this DxePcdLib
+# in their initialization without any issues to access Dynamic and DynamicEx PCD. They can't
+# access Dynamic and DynamicEx PCD in the implementation of runtime services and SMI handlers.
+# Because EFI_PCD_PROTOCOL is DXE protocol that is not available in OS runtime phase.
