Use Constraint::Equal - for example:

    elements:
        - type: Password
          name: pass1
        - type: Password
          name: pass2
          constraints:
              - type: Equal
                others: pass1

If you give a field an 'id' and a 'label' - it'll automatically give
the label a for="" attribute.
For example, this config:

id: form
auto_id: %f_%n
elements:
    name: foo
    label: Foo

produces this output:

<form action="" id="form" method="post">
<div class="text label">
<label for="form_foo">Foo</label>
<input name="foo" type="text" id="form_foo" />
</div>
</form>

auto_id() gives every field an id attribute, where %f is replaced by
the form id, and %n is replaced by the field name.
