The `autocomplete` attribute on a `<form>` element only accepts `"on"` or `"off"` as valid values — `"false"` is not a recognized keyword.

The `autocomplete` attribute controls whether the browser can automatically fill in form fields based on previously entered values. When set on a `<form>` element, it applies as the default behavior for all fields within that form. The valid values are `"on"` (the browser may auto-complete entries) and `"off"` (the browser should not auto-complete entries).

It's a common mistake to use `"true"` or `"false"` since many other attributes and programming languages use boolean-style values. However, the HTML specification explicitly defines only `"on"` and `"off"` for the `<form>` element's `autocomplete` attribute.

Note that individual `<input>` elements support a much wider range of `autocomplete` values (like `"name"`, `"email"`, `"street-address"`, etc.), but these extended values do not apply to the `<form>` element itself.

## Invalid Example

```html
<form autocomplete="false" action="/submit" method="post">
  <label for="email">Email</label>
  <input type="email" id="email" name="email">
  <button type="submit">Submit</button>
</form>
```

## Valid Example

```html
<form autocomplete="off" action="/submit" method="post">
  <label for="email">Email</label>
  <input type="email" id="email" name="email">
  <button type="submit">Submit</button>
</form>
```
