/**
 * Common attributes for JSON schema types.
 *
 * `IJsonSchemaAttribute` is a common interface for all JSON schema
 * types supported in here `@samchon/openapi`. Here is the list of
 * affected JSON schema types in `@samchon/openapi`, and you can extend
 * the interface by declaring module augmentation.
 *
 * - {@link OpenApi.IJsonSchema}
 * - {@link OpenApiV3_1.IJsonSchema}
 * - {@link OpenApiV3.IJsonSchema}
 * - {@link SwaggerV2.IJsonSchema}
 * - {@link IChatGptSchema}
 * - {@link IClaudeSchema}
 * - {@link IGeminiSchema}
 * - {@link ILlmSchemaV3}
 * - {@link ILlmSchemaV3_1}
 *
 * For example, if you extend the `IJsonSchemaAttribute` interface
 * like below, every JSON schema types in `@samchon/openapi` will have
 * a new custom attribute `x-wrtn-placeholder`.
 *
 * Also, if you augment the nested type like
 * `IJsonSchemaAttribute.IString`, you can add the custom attribute
 * to every string types in the JSON schema. In the below example case,
 * every string types will have a new custom attribute
 * `x-wrtn-secret-key`.
 *
 * ```typescript
 * declare module "@samchon/openapi" {
 *   export interface IJsonSchemaAttribute {
 *     /// Placeholder value for frontend application
 *     ///
 *     /// Placeholder ia label shown in the input field as a hint.
 *     /// For example, when an email input field exists, the label
 *     /// value would be "Insert your email address here".
 *     "x-wrtn-placeholder"?: string;
 *   }
 *   export namespace IJsonSchemaAttribute {
 *     export interface IString {
 *       /// Secret key for the schema.
 *       ///
 *       /// `x-wrtn-secret-key` is a property means a secret key
 *       /// that is required for the target API endpoint calling.
 *       /// If the secret key is not filled, the API call would
 *       /// be failed.
 *       "x-wrtn-secret-key"?: string;
 *     }
 *   }
 * }
 * ```
