title: Does OpenAPI 3 allow duplicate parameter names but in different locations (path/query/header)?
body: <p>I am not sure if I understand the specification correctly. For example, <a href="http://spec.openapis.org/oas/v3.0.3#parameter-object" rel="nofollow noreferrer">this</a> states that a unique parameter is defined by a combination of its <em>name</em> and <em>location</em>.</p>
  <p>Does that mean I can have a path parameter called &quot;hello&quot;, a query parameter called &quot;hello&quot;, and a header called &quot;hello&quot; all at the same time?</p>
