/**
 * Runtime binding for `schemas:ExportSchema`.
 *
 * Exports the bound {@link Schema} as a JSONSchema Draft 4 document —
 * useful when a function needs a portable validation schema for an event
 * contract that is registered as OpenAPI 3. The registry and schema names
 * are injected from the binding. Provide the implementation with
 * `Effect.provide(AWS.Schemas.ExportSchemaHttp)`.
 *
 * Note: AWS only allows exporting discovered or AWS-managed schemas
 * (registries `discovered-schemas` / `aws.events`). Calling it on a
 * custom-registry schema fails with a typed `ForbiddenException`
 * (`You cannot export non discovered or non aws managed schemas.`).
 * ### Reading Schemas
 * **Example:** Export As JSONSchema Draft 4
 * ```typescript
 * // init — bind the operation to the schema
 * const exportSchema = yield* AWS.Schemas.ExportSchema(schema);
 *
 * // runtime
 * const { Content } = yield* exportSchema({ Type: "JSONSchemaDraft4" });
 * const jsonSchema = JSON.parse(Content!);
 * ```
