## FORM

This is used to define an HTML form, and you can have more than one form in the same document. Both the start and end tags are required. For very simple forms, you can also use the `ISINDEX` element. Forms can contain a wide range of HTML markup including several kinds of form fields such as single and multi-line text fields, radio button groups, checkboxes, and menus.

action
  This specifies a URL which is either used to post forms via email, e.g. `action="mailto:foo@bar.com"`, or used to invoke a server-side forms handler via HTTP, e.g. `action="http://www.acme.com/cgi-bin/register.pl"`
method
  When the action attribute specifies an HTTP server, the method attribute determines which HTTP method will be used to send the form's contents to the server. It can be either `GET` or `POST`, and defaults to `GET`.
enctype
  This determines the mechanism used to encode the form's contents. It defaults to application/x-www-form-urlencoded.

Further details on handling forms are given in RFC 1867.
