 As turtle91 stated, not all elements can be nested. 
For future use, you might want to add the epubcheck plugin to calibre's editor.  It is a much better error checker than the builtin calibre error checker. See 
[Editor Plugin] EpubCheck  for information on installing, etc.
For your sample, something like the following would work (the <br /> breaks the output into two lines).
	Code:
	<h2><span class="block_21" id="calibre_pb_8">6</span><br />
    <span class="block_24">The Real Enterprise</span></h2>
