regex not working as expected with boolean fields in ValidateFormat

Hello,

I know you won't answer questions, but I tought it would be good to share this. I stumbled upon an issue with validateFormat using regex when trying to check a boolean field. I suspect this simply cannot be used for boolean fields.

More info here:

Maybe this should be stated more clearly in the docs?

Thanks and keep up the good work!
