AI Summary: The `CreateFilteredDocument` method in OpenAPI.NET currently fails to remove unused components (like schemas) after filtering operations, leading to excessively large and impractical filtered documents, especially with large specifications like the Graph API. The request is to enhance `FilterDocumentOptions` or a similar mechanism to enable more advanced filtering behavior, specifically by revamping the copy implementation to filter out these leftover, unreferenced components.

AI Summary: The `Microsoft.OpenApi.Readers` library incorrectly generates the `OpenApiError.Pointer` when a custom extension parser throws an `OpenApiException`. The pointer skips a level in the JSON path, misrepresenting the exact location of the error within the OpenAPI document (e.g., showing `#/definitions/x-tag` instead of `#/definitions/demo/x-tag`).

AI Summary: The task is to fix a bug in the OpenAPI.NET Hidi validator where duplicate `operationId` values in an OpenAPI specification are not detected. This involves modifying the validator's logic to identify and report instances of non-unique `operationId` values within the `paths` section of the OpenAPI document.
