It seems to me that the "try it" editor on orderly-json.org works
incorrectly regarding the additionalProperties attribute. It outputs

"additionalProperties": true / false

Here's a quote from the JSON schema specification, regarding the
additionalProperties attribute:

The value must be a schema. If false is provided, no additional
properties are allowed, and the schema can not be extended. The
default value is an empty schema which allows any value for
additional properties.

The spec doesn't tell what exactly is an empty schema, but "the schema
for JSON schemas" (http://json-schema.org/schema) has {} as the
default value for "additionalProperties", so I believe that the
correct output should be

 "additionalProperties": {} / false

The "additionalProperties" could also be left out at all when the
object definition is open (i.e. there's an asterisk at the end).
