Regarding the comment I posted here:
I modified the /views/home/docs/resourceDoc.cfm to display a new section of DSL in Relax.cfc. It now outputs two types of response documentation: schemas and samples. Now my docs show the expected response structure, as well as an example of a success and failure.
You can see the changes I made to make this function in the commit I made the a fork of the project:
Attached is sample of the output generated with response docs.
