/// description: \"Determines if requestor is the document owner\" expression: \"document.owner == request.auth.claims.email\"
/// Example (Logic): title: \"Public documents\" description: \"Determine whether the document should be publicly visible\"
/// expression: \"document.type != 'private' && document.type != 'internal'\" Example (Data Manipulation):
/// title: \"Notification string\" description: \"Create a notification string with a timestamp.\"
