Getting Bad Request in many cases of "custom" attributes

[Fannon]

Hi there!

Just trying out schematic ipsum and I really like the idea!

But I've got a big issue which would prevent me from using it: The Generator accepts json-schema only in a very limited way. If you use custom attributes or even features like required = [] it stops to work.

Wouldn't it be a good idea to simply ignore unknown/additional attributes?
