/** \file ap242_styled_item.cc
** Test styled_item entity from AP242 schema
** This test verifies that the generated C++ code from the ap242treat schema
** can correctly handle styled_item entities, particularly the TREAT expression
** in the WR3 WHERE rule that was problematic in the original schema.
**
** The test:
** 1. Loads an AP242 STEP file containing styled_item instances
** 2. Verifies that styled_item entities are correctly parsed
** 3. Tests both simple cases (geometric_representation_item) and complex cases
**    (set_representation_item that exercises the TREAT expression)
** 4. Validates the entity relationships and attributes
