Named Parameters With Multiple Types don't appear in documentation

The RAML 0.8 spec says that "... the value of the named parameter property MAY be an array of mappings ...", with a named parameter defined as "URI parameters, query string parameters, form parameters, request bodies (depending on the media type), and request and response headers".

I can define a named parameter to have multiple types but it does not appear in the documentation preview. Only the first type in the array is shown.

Example - not in error according to the editor panel:

#%RAML 0.8
title: Testing multiple types for named parameters.

/testResource:
  get:
    queryParameters:
      name:
        - type: string
          description: I am a string type query parameter.
        - type: integer
          description: I am an integer type query parameter, which is an alternative option.

Documentation shows only the name parameter:

QUERY PARAMETERS

name : string
