James,
Agreed I came in to this discussion only 2 days ago.
Well thanks for that explanation about the Web content environment. As a matter of fact I am aware of such constraints.

1. I thought you folks were looking for used cases for aria-header so I suggested one For the image with text that looks like a heading. So instead of an h<n> tag, will aria-header work I ask again? It may be a solution for the constrained environment you described. 

2. This discussion about aria-header  puzzled me in an email thread that seemed to be discussing labelledby.
The example  with horses on sale and mares had aria-labelledby in the code  that already had heading markup.
So I am not sure what prompted this explanation.
Thanks and regards,
Sailesh

Sailesh,
There are times when the author of the web application has no idea what 
scripting may be running on the application when it is deployed by the 
customer. Any change to the DOM hierarchy adds extra risk. This extra 
risk may make the change infeasible due to the added cost of regression 
testing the change. Adding a simple attribute to an element does not 
present the same risk so may well be preferred in these situations.
When starting with a clean slate of course using an HTML heading (h1-h6) 
is preferred - but we are not always starting with a clean slate. WCAG 
should allow us to meet the guideline so long as the solution is 
accessibility supported.

Regards,
James
