Allow custom values for "type" attribute in JSON Schema

[krodnar]

I don't see a way to add a custom values for "type" attribute in JSON Schema, e.g. File which is supported in JS/TS. Parsing schema with non-default types leads to crash. It would be very convenient to have some sort of whitelisted/allowed custom values.

Faced same issue
What we came up with is creating fake type "File" and then removing it from result string;
Not very efficient and obvious but can do the thing

Would like to have an ability to pass array of whitelisted types that are supported by target lang

You should be able to use references as specified by JSON Schema here to do definition replacement, if all you need is an alias for a user-defined type.

@KireinaHoro we already do that, but this way leads to situation when we have File interface explicitly defined, although it already exists in DOM namespace
