+*****************
+OF-Config support
+*****************
+
+Ryu has a library for OF-Config support.
+
+XML schema files for NETCONFIG and OFConfig
+===========================================
+XML schema files for NETCONF and OFConfig are stolen from LINC whose licence
+is Apache 2.0.
+It supports only part of OFConfig so that its schema files are (intentionally)
+limited such that operation attributes are allowed only in several limited
+places.
+Once our library is tested with other OFConfig switches, the schema files
+should be updated to allow operation attribute in more places.
