`style` keyword is not supported inside Schema object

[nasa9084]

According to the documentation of Schema object, a keyword style is not supported inside.
However, in the example of PathItem object, style keyword is used inside Schema.

get:
 description: Returns pets based on ID
 summary: Find pets by ID
 operationId: getPetsById
 responses:
 '200':
 description: pet response
 content:
 '*/*' :
 schema:
 type: array
 items:
 $ref: '#/components/schemas/Pet'
 default:
 description: error payload
 content:
 'text/html':
 schema:
 $ref: '#/components/schemas/ErrorModel'
parameters:
- name: id
 in: path
 description: ID of pet to use
 required: true
 schema:
 type: array
 style: simple
 items:
 type: string 

The style is not inside Schema in JSON format example so I think this is just a mistake.
Maybe like:

get:
 description: Returns pets based on ID
 summary: Find pets by ID
 operationId: getPetsById
 responses:
 '200':
 description: pet response
 content:
 '*/*' :
 schema:
 type: array
 items:
 $ref: '#/components/schemas/Pet'
 default:
 description: error payload
 content:
 'text/html':
 schema:
 $ref: '#/components/schemas/ErrorModel'
parameters:
- name: id
 in: path
 description: ID of pet to use
 required: true
 schema:
 type: array
 items:
 type: string
 style: simple

This mistake is not fiexed v3.0.3-dev, too.
