hi Ramon,

what is the advantage of your example code over use of title in tbhis case?


- Why the title is GOOD for form controls and BAD for images?
As I have explained previouslyand linked to deatiled reasoning [2], the
title and alt have different semantics

- Is it anywhere in the spec that the title attribute can convey the
accessible name for form controls but not for images?

In HTML5 [1] its says:
title attribute: "on interactive
content<http://dev.w3.org/html5/spec/content-models.html#interactive-content>,
it could be a label for, or instructions for, use of the element" it DOES
NOT say that it can be used to provide a text alternative.

In HTML 4/xhtml

an image MUST have an alt attribute otherwise its non conforming

The alt <http://www.w3.org/TR/html4/struct/objects.html#adef-alt> attribute
must be specified for the
IMG<http://www.w3.org/TR/html4/struct/objects.html#edef-IMG>and
AREA <http://www.w3.org/TR/html4/struct/objects.html#edef-AREA> elements.[4]

In HTML5, an image must have an alt alltribute unless it is inside a figure
element with a caption [3]

<figure>
<img>
<figcaption>caption text</figcaption>
</figure>

the title is allowed on any element

As I explained previously alt has a distinct semantic. Thus authoring
conformance requirements differ.

- Do you consider this behaviour is consistent?

No.
