Validate multiple EANCOM messages in an interchange

Sovos can validate one EANCOM message (between UNH to UNT) within one EANCOM interchange (UNA to UNZ). However, as the EANCOM specification permits multiple EANCOM messages in one EANCOM interchange, you can validate multiple messages.

Parse out the EANCOM message (UNH to UNT) from the EANCOM interchange (UNA to UNZ).
Add the UNB header and the UNZ trailer to the EANCOM message (UNH to UNT).
Note:
As Sovos does not validate the UNZ segment, the counter is not crucial at this stage.
Send the entire EANCOM interchange (UNB to UNZ) from step two to Sovos as input for the SignatureValidation operation.
From Sovos's response, parse out the validation response and cache this message.
Repeat steps one to four to validate the remaining EANCOM messages (UNH to UNT or UNH to UNO or UNP).
