  \<p>An application-level, HTTP-based protocol for provisioning and managing user identity information. SCIM supplies a common schema for representing users and groups and provides a REST API.\</p>
  \</div>)* sub-attribute is not allowed to be updated by the SCIM service consumer. The default value is `false`.

* `required`: an optional attribute indicating whether the SCIM sub-attribute is required to be present in the SCIM attribute. The default value is `false`.

* `dataType`: a required attribute specifying the simple data type for the SCIM sub-attribute. The following values are permitted: `binary`, `boolean`, `dateTime`, `integer`, and `string`.

* `caseExact`: an optional attribute that is only applicable for string data types. It indicates whether comparisons between two string values use a case-exact match or a case-ignore match. The default value is `false`.

A `subAttribute` element contains the following XML elements in sequence:

* `description`: a required element describing the sub-attribute.

* `mapping`: an optional element specifying a mapping between the SCIM sub-attribute and an Lightweight Directory Access Protocol (LDAP) *(tooltip: \<div class="paragraph">

  \</div>)* attribute. This element is not applicable within the `complexMultiValued` element.
