• objectclass: An array with the following keys:
  • required: Whether or not this objectclass is required. Currently, all plugin-defined schemas must be required.
• attributes: An array where each key defines the name of the attribute, and each value is an array with the following keys:
  • required: Whether or not this attribute is required for this objectclass
  • multiple: Whether or not this attribute permits multiple values
  • extendedtype: If the value for this attribute will be pulled from a model that supports extended types, the type of data to be pulled:
    • address_types
    • email_address_types
    • identifier_types
    • telephone_number_types
  • defaulttype: If the value for this attribute will be pulled from a model that supports extended types, the default type (cm_co_extended_types:name)
