/**
 * An XCCDF benchmark is loaded using the following steps described
 * in the XCCDF Specification
 * 
 * 1) Loading.Import - Import the XCCDF document into the program and build an
 * initial internal representation of the Benchmark object, Groups, Rules, and
 * other objects. If the file cannot be read or parsed, then Loading fails.
 * 
 * At the beginning of this step, any inclusion processing specified with
 * XInclude elements should be performed. The resulting XML information set
 * should be validated against the XCCDF schema given in Appendix A.
 * 
 * 2) Loading.Noticing - For each notice property of the Benchmark object, add
 * the notice to the tools set of legal notices. If a notice with an identical
 * id value is already a member of the set, then replace it. If the Benchmarks
 * resolved property is set, then Loading succeeds, otherwise go to the next
 * step: Loading.Resolve.Items.
 * 
 * 3a) Loading.Resolve.Items For each Item in the Benchmark that has an extends
 * property, resolve it by using the following steps: (1) if the Item is Group,
 * resolve all the enclosed Items, (2) resolve the extended Item, (3) prepend
 * the property sequence from the extended Item to the extending Item, (4) if
 * the Item is a Group, assign values for the id properties of Items copied
 * from the extended Group, (5) remove duplicate properties and apply property
 * overrides, and (6) remove the extends property. If any Items extends
 * property identifier does not match the identifier of a visible Item of the
 * same type, then Loading fails. If the directed graph formed by the extends
 * properties includes a loop, then Loading fails. Otherwise, go to the next
 * step: Loading.Resolve.Profiles.
 * 
 * SCAP Notes:
 * 
 *      In SCAP use of extended groups and rules is not allowed.
 *
 * 3b) Loading.Resolve.Profiles -  For each Profile in the Benchmark that has
 * an extends property, resolve the set of properties in the extending Profile
 * by applying the following steps:
 *      (1) resolve the extended Profile,
 *      (2) prepend the property sequence from the extended Profile to that of
 *      the extending Profile,
 *      (3) remove all but the last instance of duplicate properties.
 * 
 * If any Profile's extends property identifier does not match the identifier of
 * another Profile in the Benchmark, then Loading fails. If the directed graph
 * formed by the extends properties of Profiles includes a loop, then Loading
 * fails. Otherwise, go to Loading.Resolve.Abstract.
 * 
 * 3c) Loading.Resolve.Abstract - For each Item in the Benchmark for which the
 * abstract property is true, remove the Item. For each Profile in the Benchmark
 * for which the abstract property is true, remove the Profile. Go to the next
 * step: Loading.Resolve.Finalize.
 * 
 * 3d) Loading.Resolve.Finalize - Set the Benchmark resolved property to true;
 * Loading succeeds.
