Forbid creating non-AMP "amp-*" elements

[jridgewell]

Examples include:

• <amp-sticky-ad-top-padding>
• <amp-body>

These should be i-amphtml-*, the amp- tag prefix is reserved for AMP elements only. Anything else should use public classnames, if they are style-able by publishers.

Overall, great idea. I need to check - we possibly may need to exclude <amp-body> from this though. I think it's explicitly public, for PWA/SD polyfill only.

@dvoytenko @zhouyx any updates here? Thanks.

[zhouyx]

Unfortunately I'll have to exclude <amp-sticky-ad-top-padding> as well. It is documented, renaming it will bring a breaking change.
I can however add a presubmit check to prevent future non AMP element with tagName 'amp-*'. How does that sound? Or any other ideas?

[jridgewell]

Presubmit would be great. Let's deprecate <amp-sticky-ad-top-padding> (just remove documentation for the tag name) and add a public class instead.
