//! # JSON Schema Generation for DDEX Models
//!
//! This module provides comprehensive JSON Schema generation from DDEX structures
//! for validation, documentation, and cross-language type definitions. It supports
//! version-specific variations, profile-based constraints, partner preset rules, and
//! can generate TypeScript and Python type definitions.
//!
//! ## Key Features
//!
//! - **JSON Schema Draft 2020-12** and Draft-07 support for broad compatibility
//! - **DDEX Version Aware**: Generates schemas for ERN 3.8.2, 4.2, and 4.3
//! - **Message Profile Support**: Audio, Video, and Mixed content profiles
//! - **Partner Preset Integration**: Incorporates partner-specific validation rules
//! - **Multi-Language Export**: TypeScript `.d.ts` and Python `TypedDict` generation
//! - **Advanced Validation**: Pattern matching, conditional schemas, enum constraints
//!
//! ## Architecture Overview

//!
//! ## Generation Capabilities
//!
//! ### Core Schema Types
//! - **BuildRequest**: Complete DDEX build request structure
//! - **FlatRelease**: Simplified release representation
//! - **Complete Schema**: All DDEX types with cross-references
//!
//! ### Output Formats
//! - **JSON Schema**: Standards-compliant validation schemas
//! - **TypeScript**: `.d.ts` type definition files
//! - **Python**: `TypedDict` class definitions
//!
//! ## Usage Examples
//!
//! ### Basic Schema Generation
//!
//! ```rust
//! use ddex_builder::schema::{SchemaGenerator, SchemaConfig};
//! use ddex_builder::presets::{DdexVersion, MessageProfile};
//!
//! let generator = SchemaGenerator::new(
//!     DdexVersion::Ern43,
//!     MessageProfile::AudioAlbum
//! );
//!
//! let result = generator.generate_build_request_schema()?;
//! let schema_json = serde_json::to_string_pretty(&result.schema)?;
//! println!("Generated schema:\n{}", schema_json);
//! ```
//!
//! ### Advanced Configuration
//!
//! ```rust
//! use ddex_builder::schema::*;
//! use ddex_builder::presets::*;
//!
//! let config = SchemaConfig {
//!     draft_version: SchemaDraft::Draft202012,
//!     include_examples: true,
//!     include_descriptions: true,
//!     strict_validation: true,
//!     version_conditionals: true,
//!     ..Default::default()
//! };
//!
//! let spotify_preset = spotify_audio_43();
//! let generator = SchemaGenerator::with_preset(
//!     DdexVersion::Ern43,
//!     MessageProfile::AudioAlbum,
//!     spotify_preset
//! ).with_config(config);
//!
//! let result = generator.generate_complete_schema()?;
//! ```
//!
//! ### Type Definition Export
//!
//! ```rust
//! // Generate TypeScript definitions
//! let typescript = generator.generate_typescript_types(&result.schema)?;
//! std::fs::write("ddex-types.d.ts", typescript)?;
//!
//! // Generate Python definitions
//! let python = generator.generate_python_types(&result.schema)?;
//! std::fs::write("ddex_types.py", python)?;
//! ```
//!
//! ## Schema Features
//!
//! ### Validation Rules
//! - **Required Fields**: Platform-specific mandatory fields
//! - **Format Validation**: ISRC, UPC, date format validation
//! - **Pattern Matching**: Regex patterns for code validation
//! - **Enum Constraints**: Allowed values for controlled vocabularies
//! - **Conditional Logic**: Version-specific field requirements
//!
//! ### Documentation Integration
//! - **DDEX Specification**: Field descriptions from official docs
//! - **Examples**: Real-world usage examples for each field
//! - **Cross-References**: Links between related schema definitions
//! - **Version Notes**: Migration guidance between DDEX versions
//!
//! ## Performance Characteristics
//!
//! - **Schema Generation**: 1-5ms for complete schema generation
//! - **Type Export**: 5-15ms for TypeScript/Python generation
//! - **Memory Usage**: ~2MB peak for complete schema with examples
//! - **Cache Support**: Generated schemas are reusable across builds
//!
//! ## Command Line Interface
//!
//! The schema generator includes CLI support:
//!
//! ```bash
//! # Generate complete schema
//! ddex-builder schema --version 4.3 --profile AudioAlbum --output schema.json
//!
//! # Include TypeScript and Python types
//! ddex-builder schema --version 4.3 --profile AudioAlbum \
//!   --typescript --python --examples --strict
//! ```
