This is a feature request.

In React v15.6, HTMLDOMPropertyConfig, SVGDOMPropertyConfig, and ARIADOMPropertyConfig are available by import them directly, e.g. import ReactHTMLDOMPropertyConfig from 'react-dom/lib/HTMLDOMPropertyConfig'. In v16, however, they are no longer available.

I think they are not public parts of react-dom, but they are inevitable to implement https://github.com/Deschtex/html2react , a library to build React DOM from an HTML text.

See https://github.com/Deschtex/html2react/blob/master/src/react-properties-map.js#L1-L2 for how to use them.
