title: Why does http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" is not validated in W3C Validator?
body: <p>I have:</p>
  
  <pre><code>&lt;meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" /&gt;
  </code></pre>
  
  <p>On validation in <a href="http://validator.w3.org/" rel="noreferrer">http://validator.w3.org/</a> I get this error:</p>
  
  <blockquote>
    <p>A meta element with an http-equiv attribute whose value is
    X-UA-Compatible must have a content attribute with the value IE=edge.</p>
  </blockquote>
  
  <p>I am working with <strong>.NET/Razor</strong> and of course locally using <strong>IIS</strong>. Is there a way to solve this without editing any <em>web.config</em> files? 
  Thanks in forward.</p>
