Here's an example query definition:

name: types
in: query
required: false
type: array
items:
  type: string
  enum:
    - ANY
    - Type_A
    - Type_R
    - Type_S
collectionFormat: csv
default:
  - ANY
description: |
  A comma-separated list of types to search against , or the value `ANY` for all.

Looking at this now. More specifically it occurs when a default is specified, and the default is an array object.
