Usability issues with the specific semantics for "title" attribute

Hi everybody.
As the spec says, "Relying on the title attribute is currently discouraged
as many user agents do not expose the attribute in an accessible manner"
for a number issues regarding usability. But some elements heavily rely on
this attribute to convey their own meaning or for thorough native workings.
This is a huge problem for assistive technology users. In addition to this,
it makes the text of the tooltip potentially useless for common users, as
no hint is commonly associated with the presence of @title, be it relevant
or not. Finally, it is a theoretic nonsense in some cases.
I think it should be substituted by different attributes and different
implementations, which must be elaborated in a case-by-case basis. I shall
keep the specific suggestions for a following message, hoping this thread
can have a little support.
Thanks.
A.
