1.6 Applicability Statement

Use of the WS-Enumeration: Directory Services protocol extensions is suitable when searching XML representations of directory objects by means of WS-Enumeration and the granularity of resultant items is required to be lesser than the entire directory object's representation. These extensions cannot be used independently of WS-Enumeration [WSENUM], so they might not be applicable in applications that have already standardized on a protocol other than WS-Enumeration [WSENUM] for querying directory services.

The XPath 1.0-derived selection language, defined in [MS-ADDM] section 2.4, is used to specify the fragments requested out of the resultant items in the enumerate operation. This is suitable only when the data stored in a directory service could be represented as an XML document.

There is an implicit assumption that the directory service exposes semantics similar to that of a Lightweight Directory Access Protocol (LDAP) version 3 directory service [RFC2251] facilitating the use of LdapQuery language for the filter expression in the enumerate request.
