Hi Al Gilman, WAI WG,

Some notes and questions below on these comments. I have not replied to  
all comments and I'm not speaking on behalf of the CDF WG, though I think  
it would be interesting for the CDF WG to get the questions answered.

document.write() is still in DOM Level 2 HTML, why would it be gone?  
(There is no subsequent version of DOM Level 2 HTML (like DOM Level 3  
HTML) either.)

"lang" or "xml:lang" only inherit within a document, they don't inherit  
their way into child documents. The same as with CSS and other things.

No XHTML implementation supports it either. In fact, I'm not aware of any  
implementation that has full DOM Level 3 support. (And then some parts of  
DOM Level 3 are still a note and not yet a recommendation.

The whole web uses HTML. You would think that solutions for accessibility  
would also target the web as it is. Adding semantics in HTML is possible  
using the "profile" attribute and "class" attribute values. Extending  
allowed values for "rel", et cetera.

The attribute "TABINDEX" is not allowed on all elements. While I agree  
that such an extension of HTML 4 (and specifications that build on HTML 4,  
like XHTML 1 and the XHTML Modularization) would be quite useful for  
accessibility purposes I haven't seen any proposed errata from the HTML WG  
covering this change.

Also, in the above example, why not directly put it on the <object>  
element...

Which document specifies the use of XHTML 2?

Has the WAI WG raised issues with the HTML WG on this? If there are indeed  
serious accessibility problems with HTML I suggest the WAI WG makes sure  
they get resolved given that HTML is about the only language really used  
on the web. The other 0.01% percent uses XHTML 1 which is based on HTML  
and has the same semantics.

Kind regards,

Anne van Kesteren
