Short of telepathy, the definition that makes most sense will be the one
the author was claiming to use. So your practical alternative of
implementing only one is to arbitrarily misrepresent the intended
meaning of documents, albeit in small ways (so far). I just don't think
that's a good precedent to set.

They're wildly different in that "XHTML5" uses numbered headings with
sections but alters the implied importance of a heading with its nesting
position, and reuses numbered headings as subtitles; XHTML uses <h> with
<section> /or/ <h1> to <h6> in order. On the other they're incredibly
similar in that both make my head hurt just thinking about them. ;)

What's the implied difference between <aside> and <aside class="note">?
How might a UA treat them differently?
