I agree with fleitz. The users do not care about standards and the developers should focus on the users and consequently just make it work in all browsers without caring about the theoretical specification.

I just hope IE9 is released soon and finally implements round border...

You comment is wrong on many levels. Let's just start by saying that HTML spec (formerly known as HTML5) is a very practical work, more than any of the preceding specs. This was driven by the desire and the goal to "make it work in all browsers". I guess you don't remember the "if (document.layers)" days…

While true that users don't care, spec is not for the users. It is for developers and browser vendors, and they care a lot. You may not care what's under the hood of your car as long as it drives you from the point A to the point B, but believe me, countless specs are involved.
