Notable changes: - Implemented HTMLElement constructor using @rniwa's algorithm from #403. - Rewrote element upgrading to use @rniwa's algorithm from #403, and incorporated it into the rest of the upgrading considerations. - Got rid of the ability to extend SVGElement, thus allowing us to remove most mentions of namespaces from the spec. - Removed createdCallback. - Rewrote "registering elements": - Uses defineElement instead of registerElement - Preserves the constructor instead of grabbing the .prototype property and synthesizing a new constructor - No longer spread out over four separate algorithms plus registerElement; everything is now inline under defineElement - More precise about exactly how to get the custom element prototype and callbacks - Rewrote createElement and createElementNS to be replacements instead of patches, and to call the author-supplied constructor. - Removed the "All Algorithms in One Diagram" section since so many algorithms changed or were inlined into their callers. - Removed the "Custom Elements and ECMAScript 6" section since it is very obsolete and does not reflect our current thinking. - New and rewritten algorithms do not use the unorthodox INPUTS/OUTPUTS blocks, or capitalized variable names. This is kind of a nice marker of new vs. old content. Notable things *not* substantially changed: - Parser changes are not specced still, besides to say that they should construct the element using its constructor. - Lifecycle callbacks were not changed, except for removing createdCallback. - Type extensions were not removed (yet?); it seems better to have a modernized version of them that we atomically remove. - Registries were not made available everywhere. Closes #403. Closes #365. Closes #283. Closes #185. Closes #170. Closes #169. Closes #167. Closes #163. Closes #162. Closes #161. Closes #158. Clsoes #137 (modulo the fact that #165 is still open). Closes #134. Closes #133.

Per this diagram the prototype is changed after any callbacks are invoked but that is wrong per the prose.

Is this diagram useful, btw? I can't decide. My hesitation to remove it may be colored by hours I spent hand-coding it :P

I would love more diagrams in specifications and once I find a sensible way to generate them I would include them elsewhere too. It helps a lot with checking the overall flow or interdependencies.

(In reply to Anne from comment #2)
Agreed with Anne here. I think in general spec readers/reviewers/implementors really appreciate and benefit from good diagrams, so trying to provide good ones is a great goal.
(And I think diagrams are one of those things that users of the spec often end up just taking for granted when they have them; it's one of those many things that reviewers don't take time to make positive comments about. Instead, you're only going to hear from them when there's something wrong in the diagram. That suggests that if you want to measure whether a diagram is being used, you should put some easter-eggish error into it to see how many people notice and comment...)
