         <li>!webform-types-message</li>
         <li>Go to <a href=\"!create-content\">Create content</a> and add a !types piece of content.</li>

         <li>Once finished adding fields, you may want to send e-mails to administrators or back to the user who filled out the form. Click on the <em>Emails</em> sub-tab underneath the <em>Webform</em> tab on the piece of content.</li>
         <li>Finally, visit the <em>Form settings</em> sub-tab under the <em>Webform</em> tab to configure remaining configurations options for your form.
           <ul>
           <li>Add a confirmation message and/or redirect URL that is to be displayed after successful submission.</li>
           <li>Set a submission limit.</li>
           <li>Determine which roles may submit the form.</li>
           <li>Advanced configuration options such as allowing drafts or show users a message indicating how they can edit their submissions.</li>
           </ul>
         </li>
         <li>Your form is now ready for viewing. After receiving submissions, you can check the results users have submitted by visiting the <em>Results</em> tab on the piece of content.</li>
       </ul>

+/**
  * Saves submissions that fail validation as drafts.
+ *
  * When a user attempts to submit an unfinished form and auto-save is allowed,
  * automatically save the form as a draft to allow the user to complete the
  * form later. This prevents the common failure of a user trying to submit a
  * form and not noticing validation errors. The user then leaves the page
  * without realizing that the form hasn't been submitted.
+ *
  * THEORY OF OPERATION:
  * The Drupal 7 Form API lacks an easy way to rebuild the form in the event of
  * validation errors. The opertions is thus:
+ *
  * 1) The form is first displayed. If it is an existing draft,
  *    webform_client_form will generated a form to edit the draft submission.
  *    Otherwise it creates a form for a new, empty submission. As usual.
  * 2) The submit button is pressed. The form is retrieved from cache or is
  *    recreated by webform_client_form. The values from the $_POST are merged in
  *    and the validation routines are called. As usual.
  * 3) The postvalidation routine, below, detects that validation errors should
  *    be autosaved and calls the submit handlers on a copy of the form and
  *    form_state. This creates the submission, or saves to the existing
  *    submission. The original form and form_state are not modified (yet).
  * 4) If a new submission was created, the form and form_state are updated with
  *    the newly-created sid of the submission, which is returned to the
  *    browser in the hidden field [details][sid]. The form is set to not be
  *    cached, and any existing cached copy is cleared to force step 5. The form
  *    is presented with validation errors as usual.
  * 5) When the form is submitted again, the form must be rebuilt because it is
  *    not in the cache. The existing draft detection in _webform_fetch_draft_sid
  *    detects that a webform draft is being submitted, and uses its sid in
  *    preference to any other stored draft sid in the database. In the event
  *    that multiple drafts are being implemented by another module, this ensures
  *    that the correct draft is edited.
  * 6) Repeat from step 2 until the form is abandoned (leaving the draft) or
  *    successfully submitted.
