            <xsd:documentation>The following is a description of the elements, types, and attributes that compose generic UNIX tests 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>The OVAL Schema is maintained by The MITRE Corporation and developed by the public OVAL Community.

The value of 'local' limits the search scope to local file systems (as opposed to file systems mounted from an external system). The value of 'defined' keeps any recursion within the file system that the file_object (path+filename or filepath) has specified. The value of 'defined' only applies when an equality operation is used for searching because the path or filepath entity must explicitly define a file system. The default value is 'all' meaning to search all available file systems for data collection.</xsd:documentation>
                        <xsd:documentation>Note that in most cases it is recommended that the value of 'local' be used to ensure that file system searching is limited to only the local file systems. Searching 'all' file systems may have performance implications.</xsd:documentation>

                  <xsd:documentation>The file extended attribute test is used to check extended attribute values associated with UNIX files, of the sort returned by the getfattr command or getxattr() system call. It extends the standard TestType as defined in the oval-definitions-schema and one should refer to the TestType description for more information. The required object element references a fileextendedattribute_object and the optional state element specifies the extended attributes to check.</xsd:documentation>
                  <xsd:documentation>NOTE: Solaris has a very different implementation of "extended attributes" in which the attributes are really an orthogonal directory hierarchy of files. See the Solaris documentation for more details. The file extended attribute test only handles simple name/value pairs as implemented by most other UNIX derived operating systems.</xsd:documentation>

The fileextendedattribute_object will collect all UNIX file types (directory, regular file, character device, block device, fifo, symbolic link, and socket). Each object extends the standard ObjectType as defined in the oval-definitions-schema and one should refer to the ObjectType description for more information.

This is because the 'filepath' element represents an absolute path to a particular file and it is not possible to recurse over a file.</xsd:documentation>

Unix systems are generally configured to only allow a given password to last for a fixed period of time. When this time, the chg_req parameter, is near running out, the system begins warning the user at each login. How soon before the expiration the user receives these warnings is specified in exp_warn. The only hiccup in this design is that a user may not login in time to ever receive a warning before account expiration. The exp_inact parameter gives the sysadmin flexibility so that a user who reaches the end of their expiration time gains exp_inact more days to login and change their password manually.</xsd:documentation>
