1) Performance optimization for the OVAL engine, to track canonical ObjectType permutations so that it can re-play result sets instead of re-requesting from an IAdapter
2) Implement scan cancellation for the XCCDF engine
3) Add empty OVAL definitions to any XCCDF evaluation in which there is no OVAL specified, so that a SystemInfoType can be obtained in the results.
4) Performance enhancement for the Unix ProcessAdapter
5) Per closer reading of the existing specification, disable symlink traversal for pattern-based path searches
