+# Dynamic Group schema (experimental), as defined by Netscape.  See
+# http://www.redhat.com/docs/manuals/ent-server/pdf/esadmin611.pdf
+# page 70 for details on how these groups were used.
+#
+# A description of the objectclass definition is available here:
+# http://www.redhat.com/docs/manuals/dir-server/schema/7.1/oc_dir.html#1303745
+#
+# depends upon:
+#       core.schema
+#
+# These definitions are considered experimental due to the lack of
+# a formal specification (e.g., RFC).
+#
+# NOT RECOMMENDED FOR PRODUCTION USE!  USE WITH CAUTION!
+#
+# The Netscape documentation describes this as an auxiliary objectclass
+# but their implementations have always defined it as a structural class.
+# The sloppiness here is because Netscape-derived servers don't actually
+# implement the X.500 data model, and they don't honor the distinction
+# between structural and auxiliary classes. This fact is noted here:
+# http://forum.java.sun.com/thread.jspa?threadID=5016864&messageID=9034636
+#
+# In accordance with other existing implementations, we define it as a
+# structural class.
+#
+# Our definition of memberURL also does not match theirs but again
+# their published definition and what works in practice do not agree.
+# In other words, the Netscape definitions are broken and interoperability
+# is not guaranteed.
+#
+# Also see the new DynGroup proposed spec at
+# http://tools.ietf.org/html/draft-haripriya-dynamicgroup-02
