OK.

The section is now 3.17.1.1. Script languages. (The section numbering  
in the email you quoted is from the 2006-02-24 revision of the spec.)

The linked draft has become http://www.ietf.org/rfc/rfc4329

It was about <datagrid>.

I think the non-normative intro section still doesn't sufficiently  
cover the relationship to the DOM and the CSS frame tree.

It wasn't clear to me why the spec specified datagrid as part of  
required UA functionality instead of e.g. Google shipping an Open  
Source JavaScript library that implements the whole thing using  
existing stuff available in browsers. Is this about particular native  
widgets? About performance?

I thought there might be a requirement that the content made sense as  
a data model.

Not necessary, I guess.

Yes. Thanks.
