/**
 * A generic validate tag used to validate HTML.
 * If no attributes are set, then no validation occurs. If
 * no validation occurs, then this tag will fail.
 * <br/>
 * To validate a page with the title <b>Yo World!</b>:
 * <pre><source>
 *     &lt;htmlunit-validate
 *            functionId="Verify that the title is 'Yo World!'"
 *            title="Yo World!"/>
 * </source></pre>
 * If you want a better error message when a failure occurs, then pass in
 * the <b>msg</b> attribute.
 * <pre><source>
 *     &lt;htmlunit-validate
 *            functionId="Verify that the title is 'Yo World!'"
 *            title="Yo World!"
 *            msg="We must be on the wrong page."/>
 * </source></pre>
 * If you want validate that some text simple exists on the page anywhere:
 * <pre><source>
 *     &lt;htmlunit-validate
 *            functionId="Verify that 'some text' exists on the current page"
 *            textPresent="some text"/>
 * </source></pre>
 * If you want to use xpath to validate, then simply use the <b>xpath</b> attribute:
 * <pre><source>
 *     &lt;htmlunit-validate
 *            functionId="Verify that 'some text' exists on the current page"
 *            xpath="//body/table[2]/tr[@id='checking_account' and text=()='234333433']"/>
 * </source></pre>
 * You can, supply multiple attributes. If you supply multiple attributes
 * and the <b>msg</b> attribute, then the <b>msg</b> will be used on any failure.
