        <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) System Characteristics. The Core System Characteristics Schema defines all operating system independent objects. These objects are extended and enhanced by individual family schemas, which are described in separate documents. Each of the elements, types, and attributes that make up the Core System Characteristics 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 abstract item element holds information about a specific item on a system. An item might be a file, a rpm, a process, etc. This element is extended by the different component schemas through substitution groups. Each item represents a unique instance of an object as specified by an OVAL Object. For example, a single file or a single user. Each item may be referenced by more than one object in the collected object section.

            <xsd:documentation>The required id attribute is a unique (to the file) identifier that allows the specific item to be referenced.</xsd:documentation>
            <xsd:documentation>The required status attribute holds information regarding the success of the data collection. For example, if an item exists on the system then the status would reflect this with a value of 'exists'. If there was an error collecting any information about an item that is known to exist, then the status would be 'error'. An error specific to a particular entity should be addressed at the entity level and not the item level. When creating items, any entities that can successfully be collected should be reported.</xsd:documentation>
            <xsd:documentation>In some cases, when an item for a specified object does not exist, it may be beneficial to report a partial match of an item showing what entities did exist and what entities did not exist for debugging purposes. This is especially true when considering items that are collected by objects with hierarchical object entities. An example of such a case is when a file_object has a path entity equal to 'C:\' and a filename entity equal to 'test.txt' where 'test.txt' does not exist in the 'C:\' directory. This would result in the creation of a partially matching file_item with a status of 'does not exist' where the path entity equals 'C:\' and the filename entity equals 'test.txt' with a status of 'does not exist'. By showing the partial match, someone reading a system-characteristics document can quickly see that a matching file_item did not exist because the specified filename did not exist and not that the specified path did not exist. Again, please note that the implementation of partial matches, when an item for a specified object does not exist,  is completely optional.  </xsd:documentation>
