# An arbitrary 'attribute' attachable to records.  
#
# Gets support for arbitrary options via InheritableOptions.  By default it 
# has one option, +type+, but subclasses could extend for further options by
# overwriting +options_parameters+.
#
# By default, the +type+ options are managed via the +MenuOption+ class.
