The ARIA spec still doesn't say if the roles of rows, column headers  
and focusable cells are inferred when an HTML table has role=grid or  

The spec suggests that this might be intended but doesn't say so in  
clear normative prose:

> There may also be cases where ARIA can augment an existing element  
> in the host language. For example, a grid and gridcell elements can  
> reuse the functionality of a table when overlaying it. ARIA roles,  
> states, and properties are best used when the markup language does  
> not support all the semantics required. When a role attribute is  
> added to an element, the semantics and behavior of the element are  
> augmented or overridden by the role behavior.
