The following is a description of the elements, types, and attributes that compose the IOS-XE specific system characteristic items found in Open Vulnerability and Assessment Language (OVAL). Each item is an extension of the standard item element defined in the Core System Characteristic Schema. Through extension, each item inherits a set of elements and attributes that are shared amongst all OVAL Items. Each item 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 System Characteristic Schema is not outlined here. The OVAL Schema is maintained by the 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.cisecurity.org. Thanks to Omar Santos and Panos Kampanakis of Cisco for providing this test. IOS-XE System Characteristics 5.11.1:1.2 11/30/2016 09:00:00 AM Copyright (c) 2016, Center for Internet Security.
