# Base ExtractGuidedSection Library.
# This instance can also be used in SEC phase only when the memory is ready in SEC phase.
-# PCD PcdGuidedExtractHandlerTableAddress points to the available memory address
-# to store Guided Extract Handlers.
+# PCD PcdGuidedExtractHandlerTableAddress points to the available pysical memory space
+# that is used to store Guided Extract Handlers.
+# Note: A driver of type DXE_RUNTIME_DRIVER can use this ExtractGuidedSectionLib
+# in their initialization without any issues. They only have to be careful in
+# the implementation of runtime services, because this BASE library instance doesn't
+# convert the address pointed by PcdGuidedExtractHandlerTableAddress to the virtual address.
