      public @interface Persist

  Identifies a field as persistent, meaning its value persists from one request to the next. Different strategies exist for how this is accomplished, the most common being the default, "session", which stores the field's value in the `Session`. In most cases, the value will be omitted and will default to the empty string. This forces a search for the correct strategy. Starting with the component (or mixin) itself, a check is made for the `meta data property` `tapestry.persistence-strategy`. If a value is found, it is used, otherwise the search continues up the inheritance hierarchy, towards the page. If not found, then the "session" strategy is used. In this way, the session persistence strategy for a component and all of its sub-components can be controlled by the containing component.
