188.8.131.52.5 Constructed Attributes
Individual constructed attributes, other than rootDSE Attributes (section 184.108.40.206.2), are specified in [MS-ADA1], [MS-ADA2], and [MS-ADA3]. But briefly, constructed attributes have the property that they are attributes for which the attribute value is computed by using other attributes, sometimes from other objects. Regardless of this property, constructed attributes are defined to be those attributes that meet one of the following three criteria:
The attribute is a rootDSE attribute (section 220.127.116.11.2).
The attribute is a back link attribute.
The objects and attributes for specified constructed attributes are covered in this section.
