+# Chromium: Drop all the stringprep files including RFC 3491 for IDNA 2003.
+# ICU supports UTS 46 (IDNA2003, transition, and IDNA 2008), but Chromium
+# does not use IDNA 2003 any more and uses transitional/IDNA 2008 for which
+# a separate resource (uts46.nrm) is used. Therefore, we can drop rfc3491 as
+# well.
+# If we ever need to support other stringprep (e.g. LDAP, XMPP, SASL),
+# we have to add back the corresponding prep files.
+# rfc3491 : stringprep profile for IDN 2003
+# rfc3530 : NFS
+# rfc3722 : String Profile for Internet Small Computer
+#           Systems Interface (iSCSI) Names
+# rfc3920 : XMPP (Extensible Messaging and Presence Protocol)
+# rfc4011 : Policy Based Management Information Base, SNMP
