ajaxSingle | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | Boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only. Default value is "true"
align | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | This attribute specifies the position of the table with relatively to the document. Possible values are "left","center","right ". Default value is "center".
binding | false | false | `javax.el.ValueExpression` (must evaluate to `javax.faces.component.UIComponent`) | The attribute takes a value-binding expression for a component property of a backing bean

bypassUpdates | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | If "true", after process validations phase it skips updates of model beans on a force render response. It can be used for validating components input
data | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax

Default value is "true".
immediate | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | A flag indicating that this component value must be converted and validated immediately (that is, during Apply Request Values phase), rather than waiting until a Process Validations phase
