Only the development of custom edit-renderer plug-ins with these limitations is supported:
- The renderer must not be used within the context of a rendering cascade; it may only be used where invoked in direct correspondence to a UIM FIELD element.
- The renderer must not be used in the context of a UIM LIST element.
- The renderer must add no more than one form item to a form page.
- The renderer must not process code-table items.
- The renderer must not use any features of the Renderer API other than those demonstrated in this chapter.
