A good idea, but one which I feel should be addressed by the use of the 
<caption> element instead of the <title> or <h> element.

Formatting <h>'s that are not children of <section>'s is at all 
difficult in CSS.  The CSS selector :not(section)>h would do nicely.  
If you are arguing that it should not be treated semantically the same, 
well that 's one reason I favor using <caption> instead of <h> for this

Actually no, your <h> wouldn't get moved up, altho they would still 
have their heading level associated with the number of sections that 
they are embedded in.  Given the way h is being used, might it not be 
worthwhile to allow <h> to only be a child of <body> and <section>.  
The way that <section> and <h> are linked semantically certainly makes 
me think that it might be a good idea. Semantically <section><div><h> 
makes as much sense as <object><div><param> but while the first one is 
currently valid, the second is not and I have come to the conclusion 
that neither should be.
