Indeed, or more exactly, refining the meaning of an element have to  
be done in a very careful way.
For example, because we were talking about small element. Something  
that would make a bit more sense to me would be

What type of information I could see HTML 5.01


================================
   Definition: The small element renders the text in a smaller font  
than its environment.

   Browsers: They should support it by rendering with a font smaller  
than the …

   Authoring tools: They should not support this presentational  
elements. If the use of small is done in the intent of carrying  
meaningful semantics, the author should use an appropriate class name  
or a dedicated element for it.


   Example:

   Old:
      <p>
         <small>
	<a href="http://creativecommons.org/licenses/by/2.0/">Creative  
Commons 2.0</a>
	</small>
      </p>

   Preferred:
      <html profile="@@">
      …
      <p class="copyright">
	<a href="http://creativecommons.org/licenses/by/2.0/"  
rel="license">cc by 2.0</a>
      </p>
      …
    See http://microformats.org/wiki/rel-license

   Trivia: "small" elements has been used to represent sometimes  
"small print" (part of a document often describing legal  
restrictions, such as copyrights or other disadvantages), or other  
side comments.

================================


Issue:
   Here there is a need of statistics. From my [quick checking][1] on  
some high traffic japanese websites, it has been used only 1 on 8 on  
the home page. (which is not a serious survey, just to give an idea.)
   - How many small elements are really used for "small print" or  
"side comments"?
   - What is the most common way of declaring copyright information?
