<p><a href="http://jsfiddle.net/8Wf8L/" rel="noreferrer"><strong>Demo</strong></a></p>

<p>And, in case they are exactly the same, why did HTML5 add <code>srcdoc</code> attribute?</p>

<p><strong>Edit</strong></p>

<p>Maybe I wasn't clear enough. I am not comparing <code>src</code> with <code>srcdoc</code>, but <code>src</code> using text/html data URI with <code>srcdoc</code>.</p>

<p>Then, if the functionality chart is like this</p>

<pre>
 | src attribute | srcdoc attribute
 --------------------------------------------------------------------
 URL | Yes | No without using src ()
 HTML content | Yes, using data URI | Yes
</pre>

<p>why is <code>srcdoc</code> needed?</p>

<hr>

<p><strong>() Note</strong>:</p>

<p>It seems <code>srcdoc</code> can be used to load a page by URL (<a href="http://jsfiddle.net/8Wf8L/3/" rel="noreferrer">Demo</a>), using a subiframe with <code>src</code>attribute:</p>
