/**
* <!-- START SNIPPET: javadoc -->
* Render a reset button. The reset tag is used together with the form tag to provide form resetting.
* The reset can have two different types of rendering:
* <ul>
* <li>input: renders as html <input type="reset"...></li>
* <li>button: renders as html <button type="reset"...></li>
* </ul>
* Please note that the button type has advantages by adding the possibility to seperate the submitted value from the
* text shown on the button face, but has issues with Microsoft Internet Explorer at least up to 6.0
* <!-- END SNIPPET: javadoc -->

* <p/> <b>Examples</b>

* <!-- START SNIPPET: example -->
* <s:reset value="Reset" />
* <!-- END SNIPPET: example -->

*
* <pre>
* <!-- START SNIPPET: example2 -->
* Render an button reset:
* <s:reset type="button" key="reset"/>
