RE: B.2.1.1 proposal

Hi Jan,
it's really clear the concept of restricted/unrestricted. Thank you for the explanation.
Anyway I'm still thinking about this:

at the second-d) point the tool misses the feature to add the "alt " or "longdesc" fields, so definitely the tool doesn't pass the SC because it doesn't let the user to edit the content in a way that the final output will be in compliance with WCAG 2.0. 

Otherwise, in the a) point, the tool lets the author to edit raw code and it's up to him to check if the output meets the WCAG 2.0; in this case the tool passes the SC because it is "unrestricted", but Imho I believe that the author should be aware that the tool, even if it has been claimed as a "tool that generate compliant output", in this case is in "unrestricted mode" so it is not really true that the output will be really in compliance whit WCAG 2.0 rules.

The same could happen if, e.g. in the first-d) case, the CMS lets author to edit the raw code switching the tool to the "unrestricted mode": the author should be informed that he is editing the code at his own risk because he could make some mistakes and thus the final output could not be in compliance with WCAG 2.0.

So my question is: should the author be informed regarding the restricted/unrestricted state of the authoring tool and all of its consequences?

have a nice day,
Alessandro

Hi Alessandro,

I think it does make sense to explain restricted/unrestricted a bit more. Taking images as the easiest example:

Examples of Unrestricted:
(a) in a source code editor I can type whatever I like "<img src="..." alt="..." longdesc="..." myattrib="" />
(b) in a WYSIWYG editor for HTML4.01, the "Insert Image" dialog includes ALL of the HTML4.01 attributes for <img>.

Examples of Restricted but meets WCAG 2.0:
(c) in a WYSIWYG editor for HTML4.01, the "Insert Image" dialog includes just some of the HTML4.01 attributes for <img> but "alt" and "longdesc" are included in the subset.
(d) in a CMS, I can ONLY add images that I have previously uploaded to my "Asset Manager". While alt-text does not appear as an option when choose images from the "Asset Manager" to include on a page, I can add/edit the alt text at any time within the " Asset Manager".
 
Examples of Restricted but FAILS WCAG 2.0:
(d) in a WYSIWYG editor for HTML4.01, the "Insert Image" dialog has only one field "src". There is no possible way to add "alt" and "longdesc" attribute values using the tool.

Cheers,
Jan
