properties.add("Authorized By", "John Doe");
properties.add("Authorized Date", authDate);
properties.add("Authorized Revision", doc.builtInDocumentProperties.revisionNumber);
properties.add("Authorized Amount", 123.45);

expect(properties.at("Authorized").toBool()).toEqual(true);
expect(properties.at("Authorized By").toString()).toEqual("John Doe");
expect(properties.at("Authorized Date").toDateTime()).toEqual(authDate);
expect(properties.at("Authorized Revision").toInt()).toEqual(1);
