title: Newline in alt text
body: <p>Can I use some sort of line break in the alt text for an image while still adhering to the XHTML 1.0 Strict standard?</p>
  
  <p>Something like this...</p>
  
  <pre><code>&lt;img src="foo.jpg" alt="Line 1\nLine 2" /&gt;
  </code></pre>
  
  <p>I'm asking because I want to post the following screenshot on my site, but I want to include the text-only version in the alt text for SEO reasons and for the visually impaired.</p>
  
  <p><img src="https://i.stack.imgur.com/ulYiw.png" alt="http://i.stack.imgur.com/563df.png"></p>
  
  <p>I prefer the screenshot over the plain text version because it looks more visually appealing.</p>
