This schema defines the eXtensible Configuration Checklist
Description Format (XCCDF), a data format for defining
security benchmarks and checklists, and for recording
the results of applying such benchmarks.
For more information, consult the specification
document, "Specification for the Extensible Configuration
Checklist Description Format", version 1.1 revision 4.
This schema was developed by Neal Ziring, with ideas and
assistance from David Waltermire. The following helpful
individuals also contributed ideas to the definition
of this schema: David Proulx, Andrew Buttner, Ryan Wilson,
Matthew Kerr, Stephen Quinn. Ian Crawford found numerous
discrepancies between this schema and the spec document.
Peter Mell and his colleagues also made many suggestions.
