Javadoc
Creates an arbitrary HTML tag which encloses any child components.
The value attribute specifies the name of the generated tag.
If value is an empty string then no tag will be generated, but
the child components will be rendered. This differs from setting
rendered=false, which prevents child components from being
rendered at all.
There is currently no facility for adding attributes to the
generated html tag other than those explicitly supported by
the attributes on this JSF component.
Unless otherwise specified, all attributes accept static values or EL expressions.
