Other attribute names don't register

[ethanthoma]

Hello,

I am currently using reasonml and tyxml. However, tyxml doesn't support attribute names that with _ in them. To solve this I tried:

• Using data-hs and hs as indicated in the README.md but those don't work.
• Registering the elements using _hyperscript.processNode but that only works for _ and not for data-hs or hs.

Maybe I am confused about what the README.md implies. Thanks.
