Cause (Documented platform behavior): The TorchScript exporter caps opset at ONNX_TORCHSCRIPT_EXPORTER_MAX_OPSET; newer opsets are only handled by the dynamo exporter.
Fix status: documented_behavior
Other error fragments:
- To use a newer opset version, consider 'torch.onnx.export(..., dynamo=True)'.

Proposed fix: [torch.onnx] Legacy TorchScript exporter: "Exporting to ONNX opset version N is not supported ... The highest opset version supported is M. To use a newer opset version, consider torch.o
Recommended action: Use dynamo=True (current default and recommended path) or lower opset_version to the supported maximum.
