JSF view Tag
This tag is used to create the top level view. This acts as a container of all the components that are part of the view of the page. Its attribute "locale" is important in the case of making the view internationalized. We can do so by setting the locale attribute to the locale you have to present the view of the page. Suppose we set the locale attribute to "en" or "fr" then the view is presented to the user in English and French respectively. you can also set the locale dynamically and can present the view according to the user.
