Hi Team,
Simon and me made a discussion about making the (t:graphicImage)
component XHTML complaint.
Here is the thread discussion :
https://issues.apache.org/jira/browse/TOMAHAWK-1143
We need to take your opinion about that,
Have we have to make the components XHTML complaint or leave this
to the user's usage with warnings ?

+1 for a strict (but sweet-tempered) behaviour. that means:
- log a nag warning
- render a non-empty alt attribute with a "meaningful" default text
if the developer
omits the attribute (or provides an empty one)
The thing is that for h:graphicImage and t:graphicImage we have **no
idea** what a "meaningful" text would be. This is some arbitrary image
that the user has chosen. For what purpose? We don't know - unless we
embed AI software and do image recognition on the referenced file. So
for h:graphicImage and t:graphicImage we have **only** these choices:
(a) don't output ALT. This screws all blind users, but in an obvious
way so that QA departments can easily detect it and tell their
developers to add the needed alt attributes. And it is not our code
that is at fault.
(b) output empty ALT. This screws all blind users, but it cannot be
detected by validation. And it is our code that is at fault as well as
the user code.
(c) output ALT with "ha ha no description". See (b).
For cases where myfaces components are generating the image references
for their own purposes, they *know* what that purpose is. Always. So
they are always capable of attaching a valid ALT description.
Mario has suggested to me that if there is a "title" attribute on the
component, then that could be used as the alt text. That seems
reasonable; an image title should be meaningful. But that doesn't solve
the problem.
Put the filename of the referenced image in the alt? It might sometimes
work - but equally might not. And it isn't translated into the user
language. So no, this isn't really a good solution.
Regards,
Simon
