Enforce `properties.type` for tokens

[gr2m]

properties.type must always be set and be of type string. Lowercase characters, numbers, - and _ only, must start with character.

Can I try this one?

[gr2m]

sure :) Let me know if you have any questions

[Taekyoon]

@gr2m Do I have to make test code first? I think I need to do that before modifying the code

[gr2m]

Yes, that’s what I’d do
