Support the additionalProperties? facet

[rigolepe]

• A Boolean that indicates if an object instance has additional properties.
• default: true !
• no properties given means any property allowed
• regex restrictions on additional properties are possible
• If a pattern property regular expression also matches an explicitly declared property, the explicitly declared property definition prevails. If two or more pattern property regular expressions match a property name in an instance of the data type, the first one prevails.
• support //: to restrict all additional properties

@rigolepe will this feature make it possible to define types that will generate Java/Scala Maps?
e.g

myField:
  type: object
  properties:
    //:
      type: integer

would generate

var myField: Map[String, Int]

[rigolepe]

The first step will be to map any property that is not modeled in the type as

val additionalProperties: Map[String, Any]

The //: construct has a similar implementation complexity and is foreseen in this ticket as well. It will indeed look like you see it. There is no ETA for this ticket yet, the focus at this very moment is Android support.
