Declare AP214 for the existing colour/transparency output and use compatible product context entities. Supply empty name and description strings on solid and wireframe representation relationships.

Translate native material-on-right UV loops to STEP by reversing the face-bound sense for both outer and inner bounds. Keep the spline geometry and representation structure unchanged.

Discovered while working on STEP linking/import using STEPcode with a strict parser that does not accept deviations from the spec. Exported STEP files still open correctly with Open Cascade OCCT based software as well as Kisters 3DViewStation (the only ones I currently have available) - but they opened the old ones as well - presumably they are more tolerant to invalid STEP files.
