I'm not sure about the convention regarding headings in HTML5, but I wanted to know if I could add a <small> in a <h3>, like this (this could apply to any tag inside any heading tags):

<h3>Payment details <small>(this is your default card)</small></h3>

Yes, that markup validates. You can check it yourself on http://validator.w3.org/

Something to be aware of with HTML5 though is a change to the notion of block-level elements: https://developer.mozilla.org/en/HTML/Block-level_elements
