    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 ?

Manfred commented on the jira issue:
[I moved this to the email thread, so we don't have half the discussion here 
and half on the issue]

+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.


Regards,
Simon
