4.01
The citation/attribution should not be part of the blockquote element:

<blockquote cite="http://example.com/blog/hello-world">
<p>The answer is 42.</p>
</blockquote>
<p>Source: <cite><a href="http://example.com/blog/hello-world" rel="external">Hello
World</a></cite></p>

You can add a div element to group the quote and the citation, but it exists no way to associate
them semantically.
The cite element can be used for the reference of the quoted source (but not for the author
name).

The citation/attribution (e.g., the hyperlink giving the source URL) can be inside the
blockquote, but in that case it must be within a cite element (for in-text attributions) or a
footer element:

<blockquote cite="http://example.com/blog/hello-world">
<p>The answer is 42.</p>
<footer>
<p>Source: <cite><a href="http://example.com/blog/hello-world" rel="external">Hello
World</a></cite></p>
</footer>
</blockquote>

The cite element can be used for the reference of the quoted source, or for the name of the
quote’s author.
