+ * Provides a tag to override the {...@link StripesFilter} configuration
property
+ * <code>Stripes.HtmlMode</code>.
+ * </p>
+ * <p>
+ * <code>htmlMode</code> accepts any string value, however any value not equal
to <code>html</code>,
+ * case-insensitive, puts Stripes into its default mode of XHTML-compatible
output.
+ * </p>
+ * <p>
+ * Examples of the tag's use then might be:
+ * </p>
+ * <ul>
+ * <li><s:options htmlMode="html" /> produces HTML4 and HTML5 form
elements, e.g., <img src
+ * … ></li>
+ * <li><s:options htmlMode="xhtml" /> produces XHTML-compatible form
elements, e.g., <img
+ * src … /></li>
+ * <li><s:options htmlMode="default" /> produces XHTML form elements</li>
+ * </ul>
+ * <p>
+ * Typical use of the tag in context of a Stripes application follows:
+ * </p>
+ * <p>
+ * Deployer will set the application RuntimeConfiguration of
<code>Stripes.HtmlMode</code>. A
+ * deployer choosing not to set this option, defaults the Stripes application
to its
+ * XHTML-compatible format.
+ * </p>
+ * <code>Stripes.HtmlMode</code> will set the default X/HTML output for the
<strong>entire</strong>
+ * application. Individual views of the application wishing to alter the
application default will
+ * provide this tag, at or near the beginning of the view, or JSP.</p>
