{START_DATE} will output the date of the event. {PERSONS_INFO} will display info with custom fields about all the additional people including registrant. We opted for this solution because it would be crazy to add {CUSTOM_PERSON_1_FIELD_1}, {CUSTOM_PERSON_1_FIELD_2}, {CUSTOM_PERSON_2_FIELD_1}, etc... With this you can display all info in UL list that will be formatted as:
Name
Custom fields name: value
Custom field name: value...
As usual, you can try it with the test email in the Ohanah settings.
