Description

This update enhances the OpenRosa to support the name attribute specified in XLSForms. Previously, OpenRosa did not honor the name='data' setting, which affected the implementation of custom confirmation messages. By allowing this attribute to be set and recognized, we ensure that users can utilize custom confirmation messages effectively, improving the overall user experience and flexibility of the forms.

Notes

• Implemented logic to check and set the name attribute from XLSForms in the survey object.
• The existing behavior where name was not utilized has been modified to honor the name setting, defaulting to the id_string if name is not provided or is invalid.
