This also relates to my earlier proposal to separate the presentations  
and semantics of a tooltip[1], where I suggest we liaison with the CSS  
WG to encourage them to allow authors control over visual tooltips. An  
important supplement to that proposal is also my suggestion to add  
norms for interactive UAs to provide users access to document data  
that may not be presented with the current stylesheet (such as alt and  
title, etc.).[2][3] The proposal then is not to specify how  
interactive UAs present the document data, rather to require that the  
UAs expose this data in a way users can understand in the UA's  
appropriate UI. Currently UAs often provide a source view or even an  
inspector. The problem is that there are certain pieces of a document  
that are semantically more important for the user consumer to have  
access to and requiring users to delve into the document source or a  
overly rich inspector is a barrier to user comprehension of the  
document.

Take care,
Rob
