Semantically, which is more correct: a in h2, or h2 in a?

This is a simple question about HTML. What is the right/most preferable way to put a link in a header, paragraph or another HTML element?

This way:

<h2><a href="">Some Title</a></h2>

Or this way:

<a href=""><h2>Some Title</h2></a>

Answer 1

Better is

<h2><a href="">Some Title</a></h2> 

because h is element with display block and is not good practice to have block in a element.
