description: Indicates the physical or logical file location of the binary content associated with `DocumentReference.content.attachment`. This extension is intended for internal or facade-layer use, enabling a service to resolve and retrieve the file from an external storage system (e.g., file system, object storage, or network share). The extension SHALL NOT be exposed to clients; it is removed after the content is resolved and the `attachment.data` element is populated.
