• class="accCalendar" : The bootstrap class name that specifies an accessible calendar picker.
• data-name : The name value for the calendar picker. The Name attribute of the accompanying text field must match the data-name attribute value. The selected date will then be inserted into the text field.
• id : The unique ID of the element. This value is also registered as the ID of the calendar AccDC Object, making it possible to invoke the object programmatically.
  $A.reg.uniqueID.open();
// All other AccDC API properties and methods are similarly available.
