ViewHelper `. * It allows to provide multiple HTML fragments to a component, which defines * the matching named slots. ``f:fragment`` is used directly inside a component * tag, nesting into other ViewHelpers is not possible. * * Default Fragment Example * ======================== * * If the following template ``Text.html``: * * .. code-block:: xml * * * *
*

{title}

*
* *
*
* * is rendered with the following component call: * * .. code-block:: xml * :emphasize-lines: 2,5 * * * *

My first paragraph

*

My second paragraph

* * * * it will result in the following output: * * .. code-block:: xml * *
*

My title
