Dynamic validation based upon resource/extension type definition.

[dgioulakis]

Currently, Owin.Scim does not provide any validation business logic based upon resource or extension schema definitions. When you add a resource and/or extension, you must specify a concrete type of validator that implements IValidator<T>.

Can we create an abstract validator that takes a IScimTypeDefinition and adds rules according to the schema rules and canonical values?

                            default rule-set
-----------------------------------------------------------------------
required.true           |   notEmpty
canonicalValues         |   <validate using CanonicalValueComparer>

1. Is it even worth the effort?
2. This does not cover the entire specification validation. For instance, user.Locale must be a valid language tag as defined in RFC5646.
3. Should we provide additional extensibility points that allow you to create an IRuleBuilder when defining your schema?
