document.all & document.activeElement undefined in xhtml page

1. Visit the xhtml page at http://www.battlenet.com.cn/ or http://inputtools.appspot.com/main.py
2. In the address bar, type: "javascript:alert(document.activeElement);"

Expected:
The alert dialog tells document.activeElement is not undefined.

Actual:
The alert dialog tells "undefined".

document.activeElement and document.all are defined on HTML documents, see for example:

<http://www.whatwg.org/specs/web-apps/current-work/#dom-document-activeelement>
<http://www.whatwg.org/specs/web-apps/current-work/#dom-document-all>

XHTML documents are not HTML documents (open the web inspector on one of those pages and look at document.constructor, for example, and compare it with the document.constructor of a HTML page such as this one.)

So I think it is correct for document.activeElement and document.all to be undefined in an XHTML page.

[Alexey Proskuryakov]

This is incorrect.

All documents in an HTML5 compliant engine must implement HTMLDocument interface, see <http://www.whatwg.org/specs/web-apps/current-work/#documents-in-the-dom>.

[Dmitry Azaraev]

I agree with Alexey.
Even more - now activeElement it is part of partial Document interface.
And it is blocker for custom UI toolkits to use XHTML instead of HTML.

Any update on this?

[William J. Edney]

XHTML5 is the XML formulation of HTML5 and is being used out there.

It'd be nice to get this fixed. Anything I can do to help? (I'm not a C programmer, but I can write tests, etc.).

Cheers,

Same problem with window.hasFocus().
