title: Liquid Studio: How to write a JSON schema $ref to another file
body: <p>I'm trying to refer to a JSON schema located in a different file using "$ref" with Liquid Studio 2017. Both the referring JSON schema and the referred JSON schema are located within the same directory.</p>
  
  <p>I tried it using relative paths:</p>
  
  <pre><code>"$ref": "referredSchema.json/propertyName"
  </code></pre>
  
  <p>and using absolute paths:</p>
  
  <pre><code>"$ref": "file:///C:/JSON/referredSchema.json/propertyName"
  "$ref": "file:///JSON/referredSchema.json/propertyName"
  "$ref": "file:///JSON/referredSchema.json#/propertyName"
  </code></pre>
  
  <p>and a few other variations.
  None of them worked, I always get an error message "Invalid URI". Also the documentation only mentions that refs to other documents are possible without giving a reasonable example.</p>
  
  <p>So I wonder, what the expected URI format would be.</p>
