	"if": {

	}
	}
	},
	"then": {
	"required": [
	"retryAfter"
	]
	}

The spec states the retryLimit only applies to type: retry, but the constraint is missing.

This field only applies when the type field value is "retry"

edit: per below, this conditional statement shall be removed.

In reviewing the spec, we're of the opinion that neither retryAfter or retryLimit are required even when type: retry. It's good practice but there can be situations where authors may want retries to be as fast as possible, and up until circuit breaking limits of the tool invoking the workflow.

Perhaps this PR should remove both as being required?
