With thanks to the CTO of our company, Dave Longley, we have run a set
of preliminary tests across a number of browsers to determine if and
when xmlns:-style attributes are preserved.

The test ensures that attributes originating in the markup of an HTML4
document are preserved by the HTML parser and are preserved in the DOM.
The xmlns:-style attributes are then accessed via pure Javascript and
DOM-Level-1 mechanisms. Here is the test:

We have verified that xmlns:-style attributes are preserved in the
following browsers:

Firefox 3.0.9, Firefox 3.5.1, Chrome 3.0.196, Internet Explorer 7.0,
Internet Explorer 8.0, Safari 4.0, Opera 9, Arora 0.7.0, Konqeror 4.2,
Epiphany 2.22, and Android 1.5 (T-Mobile G1)

Maciej, I believe that these results were what you were expecting. Ben,
Shane, Mark, these results contradict what I asserted this morning
during the RDFa telecon.

We have not been able to test a vanilla installation of IE 5.0 or IE 6.0
 running on Windows XP SP2. The "Multiple IE" program is not guaranteed
to work - the tests worked for us, but we may have accidentally been
using the IE 7 browser engine.

Could members in the communities addressed in this e-mail please:

1. Review the test source code to ensure the test is accurate.
2. Submit test results for browsers that are not in the list above,
   or on the test page. Please specify whether the test worked and
   include your browser version string (which is available on the test
   page).

Ian, is there language in the HTML5 specification (I looked and could
not find any) that ensures that this current, widely supported browser
behavior is documented in the spec?
