W3C has a sense of humor after all

I was reading Eric Mayer's blog about the :empty pseudoclass and I had to go see what the W3C had to say about it. I came across the CSS3 Working draft on Selectors. I got to the end of 6.6.5 and noticed something odd: Section 6.6.6 was intentionally left blank. The source of the section is thus:

<h4><a name="content-selectors">6.6.6. Blank</a>
<!-- It's the Return of Appendix H!!! Run away! -->
<p>This section intentionally left blank.</p>
<!-- (used to be :contains()) -->

I don't know what Appendix H is but with a number like 6.6.6. and a comment to run away I'm not sure I want to find out.

Oh yea and I still don't know a good use of :empty is...
