| Attributes |
| Name | Required | Request-time | Type | Description |
| accesskey | no | true | java.lang.String | Access key that, when pressed, activates this component. |
| binding | no | true | javax.el.ValueExpression | Using an EL expression, bind the component reference to a bean property, so that the component may be accessed in the bean. |
| converter | no | true | javax.faces.convert.Converter | Converter is an interface describing a Java class that can perform Object-to-String and String-to-Object conversions between model data objects and a String representation of those objects that is suitable for rendering. |
| converterMessage | no | true | java.lang.String | If present, will be used as the text of the converter message, replacing any message that comes from the converter. |
| disabled | no | true | boolean | If true no input may be submitted via this component. Default = 'false'. |
| group | no | true | java.lang.String | ID of button group component if this button is outside of the button group but wants to logically belong to the group. |
| id | no | true | java.lang.String | The component identifier for this component. This value must be unique within the closest parent component that is a naming container. |
| immediate | no | true | boolean | A flag indicating that conversion and validation of this component's value should occur during Apply Request Values phase instead of Process Validations phase. Default = 'false'. |
| label | no | true | java.lang.String | Label to be displayed for the button. |
| labelPosition | no | true | java.lang.String | Position of label relative to the radio button. Supported values are "left/right/top/bottom/none". Default is "none". |

| required | no | true | boolean | A flag indicating whether the user required to provide a non-empty submitted value for this component. Default = 'false'. |
| requiredMessage | no | true | java.lang.String | If present, will be used as the text of the validation message for the "required" facility, if the "required" facility is used. |
| style | no | true | java.lang.String | The inline style of the component, rendered on the root div of the component. |

| tabindex | no | true | java.lang.Integer | Tabindex of the component. |
| validator | no | true | javax.el.MethodExpression | MethodExpression representing a validator method that will be called during Process Validations to perform correctness checks on the value of this component. The expression must evaluate to a public method that takes FacesContext, UIComponent, and Object parameters, with a return type of void. |
| validatorMessage | no | true | java.lang.String | If present, will be used as the text of the validator message, replacing any message that comes from the validator. |
| value | no | true | java.lang.Object | The current value of the simple component. The value to be rendered. |
| valueChangeListener | no | true | javax.el.MethodExpression | MethodExpression representing a value change listener method that will be notified when a new value has been set for this input component. The expression must evaluate to a public method that takes a ValueChangeEvent parameter, with a return type of void, or to a public method that takes no arguments with a return type of void. In the latter case, the method has no way of easily knowing what the new value is, but this can be useful in cases where a notification is needed that "this value changed". |
