/**
* A set of one or more tabs. A TabSet is a naming container which should contain
* only {@link Tab} components. The currently selected tab is specified via the
* {@code selected} property, which may be bound to a model value. Action listeners
* may be registered individually with a Tab; or, an action listener may be
* registered with the containing tabSet, in which case it is notified of all tab
* selection actions.
*
* TabSet implements {@link javax.faces.component.EditableValueHolder}, but it
* diverges significantly from the behavior of a typical editable value holder. Note
* that the {@code selected} property is an alias for the {@code value} property.
*
*
* - Converters and Validators. Converters and validators are not used by
* the tab set component. The value of a tab set is the ID of the currently selected
* tab, set as a result of the tab selection action. The id is always a String,
* and need not be converted. Also, since the tab always sets a correct id, the id
* need not be validated.
* - Validation and tab navigation. Tabs may contain input components. By
* default, when a new tab is selected, the tab set checks whether all input components
* inside the current tab are valid. If one or more is not valid, then the tab set
* marks itself as invalid. As a result, the selected property will not be updated,
* and the tab set will output the previously selected tab as selected. In other
* words, by default, users cannot move from one tab to another until all they have
* provided valid values for all the tab's input components.
* - Updating of bound value models. If a tab set is valid, and the value of
* the selected property is changed, a model bound to the value will be updated.
* - Immediate tab sets. If a tab set is made immediate, tab nagivation will
* be allowed to occur even if there are invalid input components inside the
* current tab. However, in this case, the model value will
not be
* updated. This generally works best if the tabs themselves are also made immediate,
* and if some other command component is used to actually submit the page for
* value processing.
