        <xsd:documentation>The following is a description of the elements, types, and attributes that compose extensions to the standard Unix OVAL schema, found in Open Vulnerability and Assessment Language (OVAL). Each test is an extension of the standard test element defined in the Core Definition Schema. Through extension, each test inherits a set of elements and attributes that are shared amongst all OVAL tests. Each test is described in detail and should provide the information necessary to understand what each element and attribute represents. This document is intended for developers and assumes some familiarity with XML. A high level description of the interaction between the different tests and their relationship to the Core Definition Schema is not outlined here</xsd:documentation>
        <xsd:documentation>This schema was originally developed by David Solin at jOVAL.org. The OVAL Schema is maintained by The MITRE Corporation and developed by the public OVAL Community. For more information, including how to get involved in the project and how to submit change requests, please visit the OVAL website at http://oval.mitre.org.</xsd:documentation>

            <xsd:documentation>The symlink_object element is used by a symlink_test to define the object to be evaluated. Each object extends the standard ObjectType as defined in the oval-definitions-schema and one should refer to the ObjectType description for more information. The common set element allows complex objects to be created using filters and set logic. Again, please refer to the description of the set element in the oval-definitions-schema.</xsd:documentation>
            <xsd:documentation>A symlink_object consists of a filepath entity that contains the path to a symbolic link file.  The resulting item identifies the canonical path of the link target (followed to its final destination, if there are intermediate links), an error if the link target does not exist or is a circular link (e.g., a link to itself).  If the file located at filepath is not a symlink, or if there is no file located at the filepath, then any resulting item would itself have a status of does not exist.</xsd:documentation>
