I couldn't easily find an answer to this question, so after some experimenting, I thought it would be appropriate to share what I've found should anyone follow after me.
The use case was to show/hide buttons on a ribbon based upon a boolean field value. Since you can represent a boolean field value with 1/0, yes/no, and true/false it wasn't immediately obvious to me which one the Ribbon Workbench would take as an input. Turns out the Ribbon Workbench only recognizes the values of
true/false when you're working with Display/Enable rules. Hopefully that helps someone else down the road.
