Question: How is validation achieved?

[mrpmorris]

I don't seem to be able to use EditForm etc.

You're right, you can't use EditForm, as it is targeted specifically for web. It is possible to create an alternative though.
There is a POC in this PR, but the code is really outdated there.

There is no built-in support, as I wasn't able to figure out a universal way to make it work with built-in and third-party elements, which already provide some validation mechanisms.

I'll try to built a sample demonstrating that soonish though.

I've added a small sample with an example how you can achieve that:
