title: Should we put <input> inside <label>?
body: <p>I saw 2 different method on same form example:</p>
  
  <p>on <a href="http://www.alistapart.com/articles/prettyaccessibleforms/" rel="noreferrer">http://www.alistapart.com/articles/prettyaccessibleforms/</a> why they are using 2 method in first <code>fieldset</code> they are keeping <code>input</code> after <code>label</code>and in 2nd <code>fieldset</code> they are keeping <code>input</code> after <code>label</code>. Why?</p>
  
  <pre><code>&lt;fieldset&gt;
    &lt;legend&gt;Delivery Details&lt;/legend&gt;
    &lt;ol&gt;
      &lt;li&gt;
        &lt;label for="name"&gt;Name&lt;em&gt;*&lt;/em&gt;&lt;/label&gt;
        &lt;input id="name" /&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;label for="address1"&gt;Address&lt;em&gt;*&lt;/em&gt;&lt;/label&gt;
        &lt;input id="address1" /&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;label for="address2"&gt;Address 2&lt;/label&gt;
        &lt;input id="address2" /&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;label for="town-city"&gt;Town/City&lt;/label&gt;
        &lt;input id="town-city" /&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;label for="county"&gt;County&lt;em&gt;*&lt;/em&gt;&lt;/label&gt;
        &lt;input id="county" /&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;label for="postcode"&gt;Postcode&lt;em&gt;*&lt;/em&gt;&lt;/label&gt;
        &lt;input id="postcode" /&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;fieldset&gt;
          &lt;legend&gt;Is this address also your invoice »
  address?&lt;em&gt;*&lt;/em&gt;&lt;/legend&gt;
          &lt;label&gt;&lt;input type="radio" »
  name="invoice-address" /&gt; Yes&lt;/label&gt;
          &lt;label&gt;&lt;input type="radio" »
  name="invoice-address" /&gt; No&lt;/label&gt;
        &lt;/fieldset&gt;
      &lt;/li&gt;
    &lt;/ol&gt;
  &lt;/fieldset&gt;
  </code></pre>
  
  <p>why they are sometime keeping <code>input</code> after <code>label</code> and sometime inside?</p>
