#/** @file
# Instance of PCD Library using PCD PPI.
#
+# There are two PCD PPIs as follows:
+# 1) PCD_PPI
+# It is EDKII implementation which support Dynamic/DynamicEx Pcds.
+# 2) EFI_PEI_PCD_PPI
+# 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_PPI and EFI_PEI_PCD_PPI.
+# This library instance uses the PCD_PPI to handle dynamic PCD request and use
+# EFI_PEI_PCD_PPI to handle dynamicEx type PCD.
+#
+# This library instance assume the PCD_PPI and EFI_PEI_PCD_PPI are both installed early.
+#
# PCD Library that uses the PCD PPI to access Dynamic and DynamicEx PCD entries
