  Name | Required | Type | Description
  --- | --- | --- | ---
  `acceptedTypes` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Defines comma separated list of file extensions accepted by component. The format of the file extension can be "png" or ".png", the second format will filter extensions in the dialog window. The component does not provide any feedback when rejecting file. For introducing feedback for rejection, use ontyperejected parameter.
  `addLabel` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The label for the Add button.
  `binding` | `false` | `javax.el.ValueExpression` (must evaluate to `javax.faces.component.UIComponent`) | The value binding expression used to wire up this component to a component property of a JavaBean class
  `clearAllLabel` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The label for the Clear button.
  `clearLabel` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The label displayed for the Clear link
  `data` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | Serialized (on default with JSON) data passed to the client by a developer on an AJAX request. It's accessible via "event.data" syntax. Both primitive types and complex types such as arrays and collections can be serialized and used with data
  `deleteLabel` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The label displayed for the Delete link
  `dir` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Direction indication for text that does not inherit directionality. Valid values are "LTR" (left-to-right) and "RTL" (right-to-left).
  `disabled` | `false` | `javax.el.ValueExpression` (must evaluate to `boolean`) | Flag indicating that this element must never receive focus or be included in a subsequent submit. Default value - "false"

  `execute` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | IDs of components that will participate in the "execute" portion of the Request Processing Lifecycle. Can be a single ID, a space or comma separated list of IDs, or an EL Expression evaluating to an array or Collection. Any of the keywords "@this", "@form", "@all", "@none", "@region" may be specified in the identifier list. Some components make use of additional keywords
  `fileUploadListener` | `false` | `javax.el.ValueExpression` (must evaluate to `javax.el.MethodExpression`) | A listener function on the server side after each file is uploaded. The listener should process files as required, such as storing them in the session/db/filesystem/ directory. The component itself does not store uploaded files, so if the listener is not implemented they are not stored anywhere
  `id` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The component identifier for this component. This value must be unique within the closest parent component that is a naming container.

  `lang` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Code describing the language used in the generated markup for this component.
  `limitRender` | `false` | `javax.el.ValueExpression` (must evaluate to `boolean`) | If "true", render only those ids specified in the "render" attribute, forgoing the render of the auto-rendered panels
  `listHeight` | `false` | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Defines height of file list. Default value is "210px".
  `maxFileSize` | `false` | `javax.el.ValueExpression` (must evaluate to `long`) | Defines the maximum allowed size of a file. Files exceeding the size will not be added in the component. Default value is 0 (no limit).

After a number of files in the list equals to the value of this attribute, "Add" button disappears and nothing could be uploaded even if you clear the whole list. In order to upload files again you should rerender the component. (Negative numbers means no limits; default value -1).
