Could be a good idea. That list from React isn't quite usable as-is. I think they are using it for other purposes but we can derive a proper list from that.

It has a bunch of duplicates values e.g.:

acceptcharset: 'acceptCharset',
'accept-charset': 'acceptCharset'

And others that aren't attributes e.g. innerHTML.

Oh, you are right.

So I look into react-dom again, and here is how react test the dom attribute: https://github.com/facebook/react/blob/c88fb49d37fd01024e0a254a37b7810d107bdd1d/packages/react-dom/src/tests/ReactDOMAttribute-test.js

But the test cases seem to be limited and might not cover all possible cases.

Here are some attribute lists that appear to be maintained: https://github.com/wooorm/html-element-attributes https://github.com/wooorm/svg-element-attributes
