  <li><code>text/plain</code></li>
 </ul>

 <p>If this attribute is specified, it overrides the {{htmlattrxref("enctype","form")}} attribute of the element's form owner.</p>
 </dd>
 <dt>{{htmlattrdef("formmethod")}} {{HTMLVersionInline("5")}}</dt>
 <dd>In image input element, this attribute specifies the HTTP method that the browser uses to submit the form. Possible values are:
 <ul>
  <li><code>post</code>: The data from the form is included in the body of the form and is sent to the server.</li>
  <li><code>get</code>: The data from the form is appended to the <strong>form</strong> attribute URI, with a '?' as a separator, and the resulting URI is sent to the server. Use this method when the form has no side-effects and contains only ASCII characters.</li>
 </ul>

 <p>If specified, this attribute overrides the {{htmlattrxref("method","form")}} attribute of the element's form owner.</p>
 </dd>
 <dt>{{htmlattrdef("formnovalidate")}} {{HTMLVersionInline("5")}}</dt>

 <dt>{{htmlattrdef("formtarget")}} {{HTMLVersionInline("5")}}</dt>
 <dd>This attribute is a name or keyword indicating where to display the response that is received after submitting the form.

 <ul>
  <li>_<code>self</code>: Load the response into the same browsing context as the current one. This value is the default if the attribute is not specified.</li>
  <li><code>_blank</code>: Load the response into a new unnamed browsing context.</li>
  <li><code>_parent</code>: Load the response into the parent browsing context of the current one. If there is no parent, this option behaves the same way as <code>_self</code>.</li>
  <li><code>_top</code>: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as <code>_self</code>.</li>
