## UserInfoRequestValidator Class

Validates a UserInfo request: extracts the access token \(per RFC 6750, either the
`Authorization: Bearer` header or the `access_token` form/query parameter, but not both\),
verifies its JWT signature and claims, asserts the `typ` header equals `at+jwt`, and
resolves the originating authentication session, authorization context and client\.

```csharp
public class UserInfoRequestValidator : Abblix.Oidc.Server.Endpoints.UserInfo.Interfaces.IUserInfoRequestValidator
