<custom item>

This is useful when submitting forms to applications requiring non-XFDL information. An example of non-XFDL information might be a SQL query statement.

Available options

All XFDL options, the xforms:input or xforms:textarea options, and any custom options can be used with custom items.

Example

This is an example of a custom item definition. It includes both an XFDL and a custom option.

   <custom:event xfdl:sid="STATUS_EVENT" 
      xmlns:custom="http://www.ibm.com/xmlns/prod/XFDL/Custom">
      <xfdl:active>off</xfdl:active>
      <custom:ID>UF45567/home/users/preferences01</custom:ID>
   </custom:event>

Usage details

1. Custom items must be in a non-XFDL namespace.
2. Custom items can also change the default namespace from the XFDL namespace URI in order to eliminate excess prefixes within the desired namespace.
3. Custom items may omit the XFDL scope identifier, but a sid attribute in the XFDL namespace must be provided in order to reference the custom item's content with the XFDL compute system. Since default namespaces are not applied to attributes, the sid attribute must still be qualified by a namespace prefix associated with the XFDL namespace URI.
4. Both XFDL options and custom options within the custom item can have computed values by using the XFDL compute attribute, which must be qualified with a namespace prefix associated with the XFDL namespace URI.
