How to describe a model in Swagger for an array with simple objects?

Question

I have a REST services to document, some of them accepts simple array like:

[
  { "name":"a" },
  { "name":"b" },
  { "name":"c" }
]

How do I describe this in Swagger model section ? I can only create 'named array' like

model {
properties: { "arr": { "type":"array", ......

but it describes data like this:

"arr": [
  { "name":"a" },
  { "name":"b" },
  { "name":"c" }
]

Tony YUEN was close, but no cigar. This is the proper definition using YAML in OpenAPI/Swagger:

  /test:
post:
  summary: test 123
  description: test 123
  parameters:
    - name: param1
      in: body
      required: true
      description: test param1
      schema:
          $ref: '#/definitions/stackoverflow'
  responses:
    200:
      description: OK

This produces:

stackoverflow2[
  {
     name: string
  }
]

Tony's example produces:

[
  stackoverflow { 
                 name: string
  }
]
