is it possible to ignore fields in Joi object's .meta() area?

[paul42]

I'm using Joi models and using this library to pass them into mongoose, and another library joi-to-swagger to turn my Joi models into definitions - to get references via that library I need to have something like:

var schema = Joi.object.keys().meta({className:'desiredRef'})

but joigoose tries to put that into a model and I get this error from mongoose:

TypeError: Undefined type `Address` at `className`
  Did you try nesting Schemas? You can only nest using refs or arrays.

is there any easy way to pluck the meta value off the Joi object or clear it out so I can pass the Joi object to Joigoose second

Thanks,
