/**
 * AXIS2C-1679 Test: Support Multipart SOAP in Code Generation Tool
 *
 * Issue: https://issues.apache.org/jira/browse/AXIS2C-1679
 * Feature Request: Support Multipart soap in code generation tool
 *                  The Apache CXF Java and .NET 4.x have support.
 *
 * Analysis (2024-11-21):
 * - Axis2/C already has complete MTOM infrastructure (axiom_data_handler_t, MTOM callbacks, etc.)
 * - Java maps xsd:base64Binary → jakarta.activation.DataHandler
 * - Gap: Native WSDL2C generator does NOT generate MTOM-aware ADB code
 * - Need: Map xsd:base64Binary → axiom_data_handler_t in generated code
 * - Need: Generate proper MTOM serialization/deserialization code
 *
 * Implementation Plan:
 * 1. Add MTOM type mapping to native code generator (following Java JavaTypeMap.java:114)
 * 2. Generate MTOM-optimized ADB serialization/deserialization
 * 3. Add command line options: --enable-mtom, --mtom-threshold
 * 4. Support MTOM annotations and configuration
