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
