MIRING validator gives an obscure message if the message fails HML schema validation #69
Description
If a message fails HML schema validation, the MIRING validator returns a popup with the message "something wrong happened". For sure the user needs to use one of the many tools/methods for validating their message passes HML schema validation first (before sending it to MIRING validator). But it would be good if the MIRING validator gave a better warning and made this more clear in the documentation. Even better would be for it to give specifics about the HML schema violation.
