Well, if you wish to say _everything_ about the <html> tag, you should
also consider its omissibility (in pre-XHTML HTML) and the attributes
id (in XHTML) and version (up to and including HTML 4.01). That would not
be relevant to accessibility, but neither is the xmlns attribute.

I won't argue with you on that.

When you advertize something on a list about accessibility, don't be
surprised at being evaluated from the accessibility point of view.

It's not an assumption, it's the defined default. Although there is no
specific principle "don't explicitly specify the default" in HTML
(as there is in some Internet contexts), it's not useful either, and
it may confuse authors. People may start thinking they _must_ include the
dir attribute, and then they mistype it.

(For right to left scripts, dir="rtl" _is_ generally useful. But that's a
different issue.)
