+# to DUID-EN or DUID-LL. It would require changing the "type" value
+# to "EN" or "LL" respectively. The "identifier" would hold a
+# DUID-EN variable length identifier or DUID-LL link layer address.
+# The values of "time" and "htype" would be ignored for DUID-EN.
+# If one wanted to use a non-default enterprise-id for DUID-EN, the

+# a "type" parameter is mandatory while specifying "server-id" map.
