title: xml:space="preserve" effect on space between XML attributes?
body: <p>I know that</p>
  
  <pre><code>&lt;a xml:space="preserve"&gt;
  &lt;b&gt;&lt;/b&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>is different than </p>
  
  <pre><code>&lt;a xml:space="preserve"&gt;
  &lt;b&gt;  &lt;/b&gt;
  &lt;/a&gt;
  </code></pre>
  
  <hr>
  
  <p>However, what about </p>
  
  <pre><code>&lt;a xml:space="preserve"&gt;
  &lt;b c='c'&gt;&lt;/b&gt;
  &lt;c   /&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>&lt;a xml:space="preserve"&gt;
  &lt;b     c='c'&gt;&lt;/b&gt;
  &lt;c /&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>I can't find documentation about how <code>xml:space="preserve"</code> affects these cases.</p>
