   No.  There are distinct differences between the elements.

* The <title> element is used to identify the document.
   A title element is like the title of a book, usually printed on the
   front cover.  Occationally, also printed inside, but it's clearly
   distinct from the headings.
* The <h> element, in combination with the section element, indicate the
   structure of the document.
   Just like in a book, headings identify sections of the chapter, or
   document.  I can kind of understand your comparison of <h> and <title>
   as being similar, but they are not the same.
* The <caption> element's text should describe the nature of the table
   or the object.
   When used in books, and other documents, they usually descibe tables
   and/or images.  This is not, in any way, similar to <h> or <title>.

   I made a similar proposal to this in December, but also included the 
<caption> element.

   As a colliery to this, might I also suggest moving the

   Again, <title> is nothing like <caption>, it is closer to <h>, but 
not the same.  If another title was added to the above example to serve 
as a heading for some additional alternate content, how would a UA know 
the difference, and also, it would just cause confusion for document
