From Paul Martz, "The attached preserves OpenFlight Object record data as UserData in the osg::Group corresponding to the Object record.

The files are:
    include/osgSim/ObjectRecordData -- The new class. Derives from Object to support .osg IO.
    src/osgPlugins/OpenFlight/PrimaryRecords.cpp -- Reads data into that class.
    src/osgPlugins/osgSim/IO_ObjectRecordData.cpp -- .osg IO support."

From Robert Osfield, made the OpenFlight read object record data optional via the -O readObjectRecordData ReaderWriter option.
