+Module produce UC2 on top of UC.
+
+UEFI 2.1 specification supersedes Inte's EFI Specification 1.10.
+EFI_UNICODE_COLLATION_PROTOCOL defined in Inte's EFI Specification 1.10 is replaced by
+EFI_UNICODE_COLLATION_PROTOCOL in UEFI 2.1.
+This module produces UC2 on top of UC. This module is used on platform when both of
+these two conditions are true:
+1) EFI 1.10 module producing UC present
+2) And the rest of modules on the platform consume UC2
