+In addition to the standard native properties, ZFS supports arbitrary user
+properties.
+User properties have no effect on ZFS behavior, but applications or
+administrators can use them to annotate pools.
+.Pp
+User property names must contain a colon
+.Pq Qq Sy \&:
+character to distinguish them from native properties.
+They may contain lowercase letters, numbers, and the following punctuation
+characters: colon
+.Pq Qq Sy \&: ,
+dash
+.Pq Qq Sy - ,
+period
+.Pq Qq Sy \&. ,
+and underscore
+.Pq Qq Sy _ .
+The expected convention is that the property name is divided into two portions
+such as
+.Ar module : Ns Ar property ,
+but this namespace is not enforced by ZFS.
+User property names can be at most 256 characters, and cannot begin with a dash
+.Pq Qq Sy - .
+.Pp
+When making programmatic use of user properties, it is strongly suggested to use
+a reversed DNS domain name for the
+.Ar module
+component of property names to reduce the chance that two
+independently-developed packages use the same property name for different
+purposes.
+.Pp
+The values of user properties are arbitrary strings and
+are never validated.
+All of the commands that operate on properties
+.Po Nm zpool Cm list ,
+.Nm zpool Cm get ,
+.Nm zpool Cm set ,
+and so forth
+.Pc
+can be used to manipulate both native properties and user properties.
+Use
+.Nm zpool Cm set Ar name Ns =
+to clear a user property.
+Property values are limited to 8192 bytes.
