@hongminhee This is awesome! I can see how this can snowball into a huge effort if you cover all the different entities around, and their properties.

It's also very, very useful! It'd fill the gaps that the official spec leaves undocumented.

It'd be super useful to include what type of data can occur in different fields. E.g. in a Note I've seen cc as omitted, null, a string, or a list of strings.
