    self.description = %(
Make explicit changes to an existing record's attributes and/or annotations.

For example, you can change annotations on a [Resource](#reference/resource), or the `uidnumber` of a [User](#reference/user).
    
Generally, Update is not used explicitly. Instead, an update is performed by the create-or-replace behavior of
statements such as User, Group, Host, Layer, etc.
