Display parameter style/explode

As an API consumer,
I want to know how operation parameters should be serialized.

OpenAPI 3.0 supports various combinations of style+explode to serialize parameters. However, Swagger UI does not display this information anywhere, so the users don't know how parameters are formatted unless they use "try it out". As a user I need to know, for example, whether a multi-value query parameter should be formatted at ?ids=1,2,3 or ?ids=1|2 or ?ids=1&ids=2 or in some other way.

Content & configuration

Swagger/OpenAPI definition:

openapi: 3.0.0
info:
 title: Multi-value array parameter
 version: 0.0.1
paths:
 /foo:
   get:
     parameters:
       - name: status
         in: query
         schema:
           type: array
           items:
             type: string
             enum:
               - available
               - pending
               - sold

         # ?status=available|sold
         style: pipeDelimited
         explode: false

     responses:
       200:
         description: ok

Begin by tracing how Swagger UI renders OpenAPI 3.0 operation parameters, using the sample definition and style/explode combinations in this issue. The work is done when the parameter display tells users how values are serialized, including the shown pipe-delimited example and other supported combinations.
