User Story

As a FedRAMP OSCAL stakeholder, I need to see code examples in the documentation, in any of the OSCAL formats that I am most familiar with (JSON, XML, or YAML) so that I can more easily understand how to properly implement FedRAMP OSCAL documents.

Goals

Add JSON and YAML OSCAL code snippets wherever there are currently only XML example snippets.
