[Bug 18669] Switch from is= to <tag if a decision has been reached among implementers

Hixie:

With regard to your (an Jonas, etc) latest proposal, did you happen to try it
out?

I just did, and as it turns out, all existing browsers fail to parse a tag name
with slashes in the string when used against createElement, querySelector, and
I suspect other such APIs. This is a non-starter - it would eliminate any
possibility of polyfills (which we already have:
https://github.com/mozilla/web-components/blob/master/document.register.js) -
and torpedo our component building initiative at Mozilla.

In my mind, any proposal that blocks us from providing a polyfill for current
browsers is out of the question.
