          <xsd:documentation>The following is a description of the elements, types, and attributes that compose the core schema for encoding Open Vulnerability and Assessment Language (OVAL) Directives. Each of the elements, types, and attributes that make up the Core Directives Schema are described in detail and should provide the information necessary to understand what each object represents. This document is intended for developers and assumes some familiarity with XML. A high level description of the interaction between these objects is not outlined here.</xsd:documentation>
          <xsd:documentation>The OVAL Schema is maintained by The MITRE Corporation and developed by the public OVAL Community.

               <xsd:documentation>The oval_directives element is the root of an OVAL Directive Document. Its purpose is to bind together the generator and the set of directives contained in the document. The generator section must be present and provides information about when the directives document was compiled and under what version. The optional Signature element allows an XML Signature as defined by the W3C to be attached to the document. This allows authentication and data integrity to be provided to the user. Enveloped signatures are supported. More information about the official W3C Recommendation regarding XML digital signatures can be found at http://www.w3.org/TR/xmldsig-core/.</xsd:documentation>
