Can a Catalog object point at a config file?

[Pellifer]

In this example below we show how a Catalog can point at a other Catalog as part of its definition. Can a Catalog also point directly at files, like a config file in the below example? @Haishi2016

apiVersion: federation.symphony/v1
kind: Catalog
metadata:
  name: app-config
spec:  
  siteId: hq
  type: config
  name: app-config
  parentName: global-config
  metadata:
    asset: use-case
  properties:
    line: <line-config>
