 * Test case for AXIS2C-1373: Name matching fails with choice element

 * This test reproduces the exact scenario from the Jira issue:
 * - Complex choice type with multiple elements (similar to Exchange Web Services)
 * - Verifies that the native C generator doesn't create artificial "Choice" types
 * - Ensures proper QName matching during deserialization
 * - Tests that real XML with actual choice element names can be processed
