How to use the extra formats?

[goloroden]

Apparently, schemasafe has support for the alphanumeric format. However, if I use it within a schema, my application crashes with the following exception being thrown:

Error: Unrecognized format used: "alphanumeric" at #/properties/contextIdentifier/properties/name

Now what caught my eye in the source code is that alphanumeric is a so-called extra format. What does that mean? Do I have to enable it somehow, to make it work, or …?

Am I missing something here?

I've figured it out, you have to provide extraFormats: true as part of the options object, then it works.

Yeah, this is in rc state mostly due to documentation being in progress.
Documentation on options just landed: Options.md.
