The option attributes can either be defined directly on this component
(via the itemValue, itemLabel, itemDescription properties) or the value
property can reference a SelectItem object (directly or via an EL expression).
The value expression (if defined) is read-only; the parent select component
will have a value attribute specifying where the value for the chosen
selection will be stored.
| Attributes |

| itemDescription | false | false | java.lang.String | An optional description for this item.
For use in development tools. | 
| itemDisabled | false | false | java.lang.String | Determine whether this item can be chosen by the user. | 
| itemLabel | false | false | java.lang.String | Get the string which will be presented to the user for this option. | 
| itemValue | false | false | java.lang.String | The value of this item, of the same type as the parent component's value. | 
| value | false | false | java.lang.String | An EL expression that refers to a javax.faces.model.SelectItem instance. | 
| id | false | false | java.lang.String | An identifier for this particular component instance within
a component view. 
The id must be unique within the scope of the tag's enclosing
NamingContainer (eg h:form or f:subview). The id is
not necessarily unique across all components in the current view
 
This value must be a static value, ie not change over the lifetime
of a component. It cannot be defined via an EL expression; only
a string is permitted.
