Failed to decode ISO 15118-2 EXI messages into XML

[eventlog.csv](https://github.com/user-attachments/files/21405171/eventlog.csv)

Description:

I'm running the run-sil-dc.sh example.

The issue I'm facing is with decoding ISO 15118-2 messages from EXI to XML in the session log:

- All messages sent from the EV to the EVSE are successfully decoded.

- However, most messages from the EVSE to the EV fail to decode.

For decoding and analysis, I used two tools: EXIficient GUI and V2Gdecoder (https://github.com/FlUxIuS/V2Gdecoder.git), both using schemas downloaded from https://standards.iso.org/iso/15118/.
Both tools produce the same results

Successfully decoded EVSE→EV messages:

- SupportedAppProtocolRes

- PreChargeRes

- PowerDeliveryRes

- SessionStopRes

- PaymentServiceSelectionRes

Failed to decode EVSE→EV messages:

- SessionSetupRes

- ServiceDiscoveryRes

- AuthorizationRes

- ChargeParameterDiscoveryRes

- CableCheckRes

- CurrentDemandRes

- WeldingDetectionRes

I'm unsure whether the problem lies with the decoding tools or if something went wrong during the simulation.

Please see the attached session log for details.
