SCIM provides a schema for representing the service provider's
configuration, identified using the following schema URI:
"urn:ietf:params:scim:schemas:core:2.0:ServiceProviderConfig".
The service provider configuration resource enables a service
provider to discover SCIM specification features in a standardized
form as well as provide additional implementation details to clients.
All attributes have a mutability of "readOnly". Unlike other core
resources, the "id" attribute is not required for the service
provider configuration resource.
