I hope YAML Implementers will read this and give thought to adding proper support for Schemas (http://yaml.org/spec/1.2/spec.html#Schema http://yaml.org/spec/1.2/spec.html#Schema) -- they should be customizable by the application. This would resolve a number of complaints and improve interoperability.
