type is required with patternProperties

[LarsBV]

If you write

foobar {
    properties: {
         name: { type: 'string'}.
         files: {
               patternProperties: {
                     "^[a-z]+$": {
                           filename: {type:'string'}
                     }
                }
         }
    }
}

then you have too add,
foobar.type = 'object'

even though:

hello: {
    properties: {
        message: {type: 'string'}
    }
}

doesn't require it. After having been bitten by it, this late evening, I think it should have a consistent
behavior.

At the same time a nice error message when no validators have been found would be nice.
Currently if the scheme doesn't match up, atleast in my case, it outputs 'Cannot read property 'validators' of undefined'

Sorry for delay.
Yes, error messages can be more informative. I have plans to do it.
