RAML 200 Tutorial

I’ve defined a collection resourceType according to the RAML 200 Tutorial like so:

collection:
get?:
responses:
200:
body:
application/json:
type: <<resourcePathName |!singularize>>

However I would like to also support adding an example. I’ve tried multiple variations, including

example: <<resourcePathName |!singularize>>

and

example: <>

But the compiler keeps complaining that it’s expecting an array. Does the language support this? And if so, can someone please provide a working example?
