I have now linked my GitHub and W3C accounts, but I do not have privs to revalidate the failing IPR check.

I see a bunch of links that point to the WHATWG HTML spec. Are these pages unavailable in the W3C HTML spec?

Zoe, if you post review comments on the specific line, it will be easier to track this down. I found one link (repeated twice) to the Reflection definition. Is this what you meant by "a bunch"? I linked the WHATWG version b/c the W3C spec is frequently out-of-date, but for the purposes of this reference, the W3C version will do. Added commit c424047.

@cookiecrook sorry for not being clearer before—will add line comments next time. My use of “a bunch” was incorrect, just tried to cover my butt in case I missed one 😬.

Thanks for fixing it.

Can you clarify why [Reflect] was removed?

Is it because the semantics were wrong, or is it because the IDL syntax doesn't officially support reflecting attributes whose property names don't match?

[Reflect] was removed because it's non-standard IDL, but FWIW, the WebKit and Chrome engines are both likely to use the previous iteration of this PR that included reflection attribute names.

Thanks. I see now that this more or less matches how other specs are written. [Reflect] isn't part of the official WebIDL spec, so the definition of each attribute explicitly indicates that it reflects a content attribute.
