* is defined at runtime. This also means that you can define
* <b>one</b> template file for <b>all</b> your forms. That template
* should contain a block for every element 'look' appearing in your
* forms and also some special blocks (consult the examples). If a
* special block is not set for an element, the renderer falls back to
* a default one.
