<!--XXX
what does <label> _mean_? how about an empty one, one which contains
more than one control, no controls?
-->
<p>The <code><a href="#label">label</a></code> represents a caption in a
user interface. The caption can be associated with a specific form
control, known as the <code><a href="#label">label</a></code> element's
<dfn id=labeled>labeled control</dfn>.
<p>Unless otherwise specified by the following rules, a <code><a
href="#label">label</a></code> element has no <a href="#labeled">labeled
control</a>.
<p>The <dfn id=for title=attr-label-for><code>for</code></dfn> attribute
may be specified to indicate a form control with which the caption is to
be associated. If the attribute is specified, the attribute's value must
be the ID of a <a href="#labelable" title=category-label>labelable
form-associated element</a> in the same <code>Document</code> as the
<code><a href="#label">label</a></code> element. If the attribute is
specified and there is an element in the <code>Document</code> whose ID is
equal to the value of the <code title=attr-label-for><a
href="#for">for</a></code> attribute, and the first such element is a <a
href="#labelable" title=category-label>labelable form-associated
element</a>, then that element is the <code><a
href="#label">label</a></code> element's <a href="#labeled">labeled
control</a>.
<p>If the <code title=attr-label-for><a href="#for">for</a></code>
attribute is not specified, but the <code><a
href="#label">label</a></code> element has a <span>labelable
form-associated element</span> descendant, then the first such descendant
in <a href="#tree-order">tree order</a> is the <code><a
href="#label">label</a></code> element's <a href="#labeled">labeled
control</a>.
<p>The <code title=attr-fae-form><a href="#form0">form</a></code> attribute
is used to explicitly associate the <code><a
href="#label">label</a></code> element with its <a href="#form-owner">form
owner</a>. The <code title=attr-fe-name><a href="#name11">name</a></code>
attribute represents the element's name.
<p>The <dfn id=htmlfor title=dom-label-htmlFor><code>htmlFor</code></dfn>
DOM attribute must <a href="#reflect">reflect</a> the <code
title=attr-label-for><a href="#for">for</a></code> content attribute.
<p>The <dfn id=control title=dom-label-control><code>control</code></dfn>
DOM attribute must return the <code><a href="#label">label</a></code>
element's <a href="#labeled">labeled control</a>, if any, or null if there
isn't one.
