#validate!(all = true) ⇒ Object

hack: bump off validate! for Attributes - maybe better way of doing this however, without this, tries to validate Attribute to :kind specified, e.g. if you have

has :date, :kind => Date

it will fail because Attribute is not a kind of Date - obviously, I have to think about this some more :S

at least, I could hand roll a custom validate! method for Attribute
